<PRE><B>Question 1009919</B>
f(x)=x , g(x)=x-3 , h(x)=x^2-9 , k(x)=2x. 

Find each value. 
A). g(f(-1)) = g(-1) = -4
---------------------------------
B). f(g(2)) = f(2-3) = f(-1) = -1
----------------------------------------- 
C). g(k(3)) = g(2*3) = g(6) = 6-3 = 3
----------------------------- 
D). h(g(3)) = h(3-3) = h(0) = 2*0 = 0
-------------------------
