Question

Hi, how do i find the domain and range and determine if they are both all real numbers?

Answer 1

We want to obtain the domain and range of the graphed function.

The function graphed is defined on the interval from x = -6 to +2 .

Therefore, the domain of the function is;

`\lbrack-6,2\rbrack`

The y-values of the function is on the interval from y = -2 to +2

Therefore, the range of the function is;

`\lbrack-2,2\rbrack`
