Answer:
I will just show you how to substitute.
Step-by-step explanation:
all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.
So an example of an equation for one of your number is:
you then want to plug the number after f for the x's. (I'm doing f(-3).
You then should get the equation above.
after that you solve.
just follow these steps and you should be fine :))
