Question

Given f(x) = 4x - 3, find f(-5).

Answer 1

f(-5)=4(-5)-3, so f(-5)=-20-3.
f(-5)=-23

Answer 2

The answer is

- 23

Explanation:

f(x) = 4x - 3

To find f( - 5) substitute the value of x that's - 5 and solve for f(-5)

That's

`f( - 5) = 4( - 5) - 3`

`= - 20 - 3`

We have the final answer as

`f( - 5) = - 23`

Hope this helps you
