Answer:

The domain is the set of values you put into the function.

The range is the set of values the function outputs.

<u>Example problem</u>:

Find the range of this function: y = 2x + 3, x > 0

The x > 0 part is the domain, so this means that only positive values of x can be inputted in the function.

If only positive values can be inputted in the function, then the range will be: y > 3

In this question, it is given that

A new youth activity center is being built in oak valley. the perimeter of the rectangular playing field is 332 yards. the length of the field is 5 yards less than double the width.

Let the width is x yards . And length is 5 yards less than double the width, so length is (2x-5) yards .

Perimeter is the sum of all sides, that is

$x+2x-5+x+2x-5 = 332
\\
6x-10 = 332
\\ 6x = 342
\\
x = 57 yards$
