Verified answer

1. f(x) = −4x − 2

2. -4(-3)-2

3. 12-2

4. 10

Hope this helps!

What that basically says is find the function of x when x=3.

So:

f (3) = -4 (-3) - 2

=12 - 2

=10

10.

Just substitute -3 for X:

(-4) x (-3) - 2

12 - 2 =10

(Don't forget a negative times a negative is a positive.)
