Question

Find f(-7) if f(x) = 2x 8.

Answer 1

f(-7) = 2x + 8, f(-7) = 2(-7) + 8, f(-7) = -14 + 8, f(-7) = -6 Hope this helps you out, I didn't know if there was a plus sign between 2x and 8 but hope this helps you out!

Answer 2

`f(-7)=-6`

Explanation:

we have

`f(x)=2x+8`

substitute the value of
`x=-7` in the function

`f(-7)=2(-7)+8=-6`

`f(-7)=-6`
