Hope this helps
(-3,2) bc that is the reflection of the two number all you do is baically flip the numbers
Answer:

Step-by-step explanation:
(f g)(x) is equal to f(x) times g(x). So you just need to multiply both of the equations together. Use the foil method to multiply (x+2)(x-4)

I have attached an image to better explain the foil method
32+48 = 80
Four equivalent expressions are:
40+40 = 80
20+60 = 80
10+70 = 80
30+50 = 80
