Anyone,

If you could help me with several questions that I have. They are as follows:

1) What is the range of (fog)(x) if f(x) = x(squared) + 3 and g(x) = x+4

2) What is g(x) =f-1(x) (the one is supposed to be for inverse not a negative number) if f(x) = 1/2x

3) Consider g(x) =(x+2)(cubed) + 3; what is the new equation for g(x) if it is shifted up 6 units and shifted right nine units

4) What is the range of (fog)(x) if f(x) = x(squared) + 3 and g(x) = x+4

5) What is f(x) if f(x) = z(x) +2 and z(x) = 2x-3

Any Help on these questions would be most appreciated.
