Find the domain and the range of the following: x y
3 2
5 7
1 4
9 2
3 7

Given:

The table of values.

To find:

The domain and range.

Solution:

The set of input values or x-values are known as domain.

In the given table, possible values of x are 1, 3, 5 and 9. So,

Domain = {1, 3, 5, 9}

The set of output values or y-values are known as range.

In the given table, possible values of y are 2, 4 and 7. So,

Range = {2, 4, 7}

Therefore, Domain = {1, 3, 5, 9} and Range = {2, 4, 7}.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
