Question

ILL GIVE YOU BRAINLIST !!!!

Answer 1

$\bf Step-by-step~explanation:$

Let's look at (a) first. Since -5 is in parenthesis, we have to replace x with -5. You do the same thing on (b): replace x with 2.

$\bf Step~1~(a):$

We have to replace x with -5.

$\bf f(x)=x^2-2x\\f(-5)=(-5)^2-2(-5)\\f(-5)=25-2(-5)\\f(-5)=25+10\\f(-5)=35$

$\bf Step~2~(b):$

We have to replace x with 2 now.

$\bf f(x)=x^2-2x\\f(2)=2^2-2(2)\\f(2)=4-2(2)\\f(2)=4-4\\f(2)=0$

$\large\boxed {\bf Our~final~answer:~f(-5)=35; ~f(2)=0}$
