<PRE><B>Question 764988</B>
F(x) =x^2+2x+4 ; g(x)=sqrt(9-x) 
Find each of the following if it exists: 
My question is (fg)(-7)
--------
That is either fog(-7) or it is f*g(-7)
----
If it is fog(-7) you get:
f[g(-7)] = f[sqrt(16)] = f(4) = 4^2+2*4+4 = 28
------
If it is f*g(-7) = f*4 = 4x^2+8x+16
