Hello all, I need the answer to the following equation, I'd very much appreciate it!
find A)f o g and b) g o f given F(x) = square root of (x+4) and g(x) = x^2 - 4
if you could give me the answer and briefly go over the steps in finding the equation, i'd be glad! (Talking)

do you understand what fog and gof means....it is easy...just replace in the place of x the other function
ie. gof(x): get g(x) as function and instead of x replace (substitute) the whole f(x) as it is......same for fog revise the chaper of the composite functions pls.

If, for example,and
then fog(x)= f(x^3+ 2x)= 3(x^3+ 2x)^2- (x^3+ 2x)+ 6[/tex] and
.
bump. are both f o g and g o f = to x?

You answer your own question by looking at two examples:Quote:
