Chapter 1, Problem 38CR

To determine

Each relation as a table $\left[\left(3,6\right),\left(4,12\right),\left(5,18\right)\right]$ , and determine the domain and range.

Explanation of Solution

GIVEN:

  $\left[\left(3,6\right),\left(4,12\right),\left(5,18\right)\right]$

Concept Used:

In rectangular coordinate system any point be in the form of $\left(x,y\right)$ .

• In Quadrant I, both the coordinates of ordered pair are positive, that is, $\left(+,+\right)$ .
• In Quadrant II, first number is negative and second is positive, that is, $\left(-,+\right)$ .
• In Quadrant III, both the coordinates of ordered pair are negative, that is, $\left(-,-\right)$ .
• In Quadrant IV, first point is positive and second is negative, that is, $\left(+,-\right)$ .

The relation as a table:

x	y
3	6
4	12
5	18

In order to determine the domain and range, in the given ordered pair the x-coordinate is domain and the y-coordinate is range .

So, the domain is $\left\{3,4,5\right\}$ and the range is $\left\{6,12,18\right\}$ .
