Question 1065686: Find the rules for the composite functions f ○ g and g ○ f.
f(x) = 4x^2 + 7x + 7; g(x) = x + 9
f ○ g= ??
g ○ f= ?? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! For f o g, put the g in for every x in f
That would be 4 (x+9)^2+7 (x+9)+7= 4x^2+25x+151
-----------------
For g o f, put the f in for every x in g
4x^2+7x+7+9=4x^2+7x+16.
