They are inverses if f( (g(x)) = x
f((g(x)) = (1/2) (2x + 4) - 2 = x + 2 - 2 = x
so this proves that g(x) is the inverse of f(x)
the other inverse g((f(x)) should also be = x
I can not see the picture so i caN NOT HELP SORRY
Answer:


Step-by-step explanation:
Given
The attached table

This represents an inverse function.
So, we look into x row for its value.
i.e.


Just like (a)
---- by looking into the x rows

So:


54 because the formula for the area of triangle is 1/2bh so you just substitute the b and h for 18 and 6
