Chapter 1.1, Problem 17E

To determine

To find: the relation of the values as table, equation and graph it..

Answer to Problem 17E

x	1	2	3	4	5	6	7	8	9
y	3	6	9	12	15	18	21	24	27

  $y=3x$

  

Explanation of Solution

Given information:The domain is all positive value less than 10, x is a member of domain and range is 3 times of x.

Calculation:

On multiplying each element of domain by 3, the range will be as follows:

  $\{3,6,9,12,15,18,21,24,27\}$

The relation can be represented in table of values form as follows:

x	1	2	3	4	5	6	7	8	9
y	3	6	9	12	15	18	21	24	27

The relation can be represented in equation form as follows:

  $y=3$ , where $x\in \mathbb{Z}$ and $1\le x\le 9$

On plotting the table values on a graph, the graph relation can be represented as follows:
