Answer:


\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
