Chapter 1, Problem 9STP

To determine

To find: Domain and range

Answer to Problem 9STP

Domain $=\left\{-6,-3,1,3,4\right\}$

Range $=\left\{-5,-3,1,2,4\right\}$

Explanation of Solution

Given information:

  

Concept used:

We know that a number line always starts with 0 and increases 1 unit at every interval.

Also, when two number lines intersect each other at right angle, it forms a coordinate plane. The vertical number line in this case is known as y-axis and horizontal number line is known as x-axis.

Calculation:

Basis the above definitions we can locate the point K on graph and write its ordered pair.

  

There given ordered pairs are $\left(-3,-5\right),\left(3,-3\right),\left(4,2\right),\left(1,4\right)\text{and }\left(-6,1\right)$

We know domain is represented by set of all x-coordinates and range is given by set of all y-coordinates.

Therefore,

Domain $=\left\{-6,-3,1,3,4\right\}$

Range $=\left\{-5,-3,1,2,4\right\}$
