Question

If f(x) = –8 – 5x, what is f(–4)?

f(–4) = 12

f(–4) = –28

f(–4) = 28

f(–4) = –12

Answer 1

The answer is f(-4) = 12

Answer 2

The correct option is 1.

Explanation:

The given function is

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

We have to find the value of f(-4).

Substitute x=-4 in the given function, to find the value of f(-4).

`f(-4)=-8-5(-4)`

On simplification we get

`f(-4)=-8+20`

`f(-4)=12`

The value f(-4) is 12. Therefore the correct option is 1.
