Question

Given f(x)=2x-2, find f (-3)

Answer 1

-8

Explanation:

f(-3) = 2(-3)-2

f(-3) = -6 -2

f(-3) = -8

Answer 2

`\huge{f( - 3) = - 8}`

Explanation:

`f(x) = 2x - 2`

In order to find f(-3) we substitute the value of x that's -3 into f(x) that's wherever we find x in f(x) we substitute it with -3 and solve for f(-3).

We have

`f( - 3) = 2( - 3) - 2 \\ = - 6 - 2 \\ = - 8`

We have the final answer as

`\bold{f( - 3) = - 8}`

Hope this helps you
