Question

Evaluate f(x)=x-5 when x= -5, x=0, and x=5When x= -5, f(x) = when x=0, f(x) =and when x= 5, f(x) =

Answer 1

Given the function:

`f(x)=x-5`

If we have that x = -5, then evaluating -5 on the function we get:

`f(-5)=-5-5=-10`

in a similar way, we can find f(0) and f(5):

`\begin{gathered} f(0)=0-5=-5 \\ f(5)=5-5=0 \end{gathered}`

thus, when x = -5, f(-5)=-10

when x = 0, f(0) = -5

and when x = 5, f(5)= 0
