Question

If f(x) = 2(x − 5), find f(8). 4 6 8 16

Answer 1

`\large \boxed{\mathrm{6}}`

Explanation:

`f(x)=2(x-5)`

Replace x with 8 to find f(8).

`f(8)=2(8-5)`

Evaluate.

`f(8)=2(3)`

`f(8)=6`

Answer 2

f(8) = 6

Explanation:

Plug in 8 as x in the function:

f(x) = 2(x − 5)

f(8) = 2(8 - 5)

f(8) = 2(3)

f(8) = 6
