What Is The Domain Of The Relation Graphed Below – The orthogonal coordinate systemA system of two number lines at right angles that specify points in a plane using ordered (x,y) pairs. consists of two lines of real numbers that intersect at right angles. The horizontal number line is called the x-axis. The horizontal number line serves as a reference in a rectangular coordinate system. , and the vertical number line is called the y-axis. The vertical number line is used as a reference in a rectangular coordinate system. . These two number lines define a flat surface called a plane. The planar surface defined by the x and y axes. , and each point on this plane is associated with an ordered pair of (x,y)-pairs that specify position relative to the origin on a rectangular coordinate plane. of real numbers (

Coordinate. The intersection of the two axes is called the origin. The point where the x and y axes intersect is denoted by (0, 0). , which corresponds to the point (0, 0).

Divide the plane into four areas called quadrants. The four regions of a rectangular coordinate plane bounded in part by the x and y axes and numbered with Roman numerals I, II, III, and IV. , named with the Roman numerals I, II, III, and IV, as shown. The ordered pair (

) represents the position of the points relative to the origin. For example, the ordered pair (−4, 3) represents the position 4 units to the left of the origin and 3 units above in the second quadrant.

This system is often referred to as the Cartesian coordinate system. This term is used in honor of René Descartes to designate the rectangular coordinate system. , named after the French mathematician René Descartes (1596-1650).

Next we define a relation, an arbitrary set of ordered pairs. like any set of ordered pairs. In the context of algebra, the relationships of interest are sets of ordered pairs (

) in the rectangular coordinate plane. Typically, the coordinates are related by a rule expressed using an algebraic equation. For example, the two algebraic equations y=|x|−2 and x=|y|+1 define relationships between

The solution sets of each equation form a relation consisting of an infinity of ordered pairs. We can use the solutions of given ordered pairs to estimate all other ordered pairs by drawing a line through the given points. Here we put an arrow at the ends of our lines to indicate that this set of ordered pairs persists indefinitely.

The representation of a relationship on a rectangular coordinate plane, as shown above, is called a graph. Visual representation of a relationship on a rectangular coordinate plane. . Each curve drawn on a rectangular coordinate plane represents a set of ordered pairs and thus defines a relationship.

Consider the relations consisting of the seven ordered even solutions of y=|x|−2 and x=|y|+1. The correspondence between the domain and the respective area can be represented as follows:

Note that each element in the domain of the solution set of y=|x|−2 corresponds to a single element in the interval; it’s a feature. On the other hand, solutions of x=|y|+1 have values in the domain that correspond to two elements of the domain. especially the

The vertical line test allows us to visually identify functions based on their plots. If a vertical line intersects the graph more than once, the graph is not a function. . If a vertical line intersects the graph more than once, the graph is not a function.

The vertical line represents a value in the domain, and the number of times it crosses the graph represents the number of values it matches. As we can see, each vertical line intersects the graph of y=|x|−2 only once; it is therefore a function. A vertical line can cross the graph of x=|y|+1 more than once; so it is not a function. As in the photo that

Also, since we can find a vertical line that intersects the graph more than once, we conclude that the graph is not a function. There is a lot

If the value is the input that produces exactly one output, we can use the function notation f(x)=y, which says “f of x is equal to y”. Given a function, y and f(x) can be used interchangeably. :

. We have found that the solution set of y=|x|−2 is a function; Therefore, using function notation, we can write:

In the domain, we can quickly calculate the corresponding values in the range. As we have seen, functions are also expressed by graphs. In this case we interpret f(−5)=3 as follows:

Remember that when evaluating, it’s a good idea to first replace variables with parentheses, and then replace the appropriate values. This helps with the order of operations when simplifying expressions.

At this point it is important to note that in general f(x+h)≠f(x)+f(h) holds. The previous example with g(x)=x2 illustrates this well.

The horizontal number line is referred to as the x2 axis and the vertical number line is referred to as the y3 axis. These two number lines define a plane surface called plane4, and each point of this plane is associated with an ordered pair5 of real numbers ((x,y)). The first number is called the (x) coordinate and the second number is called the (y) coordinate. The intersection of the two axes is called the origin6, which corresponds to the point ((0, 0)).

The (x) and (y) axes divide the plane into four areas called quadrants7, labeled with Roman numerals I, II, III, and IV as shown. The ordered pair ((x, y)) represents the position of the points with respect to the origin. For example, the ordered pair ((−4, 3)) represents the position (4) units to the left of the origin and (3) units above in the second quadrant.

Like any set of ordered pairs. In the context of algebra, the relations of interest are sets of ordered pairs ((x, y)) in the rectangular coordinate plane. Typically, the coordinates are related by a rule expressed using an algebraic equation. For example, the algebraic equations (y = |x| − 2) and (x = |y| + 1) define the relationships between (x) and (y). Here are some integers that satisfy both equations:
