of course.

Let's do this in 2 steps. 1. Find the composition of g and f. In other words, let the function f(x) be the input to function g(x). Show your work. 2. Simplify your answer. Now, let x=8.

OpenStudy (imterribleatmath):

Im sorry but i have no clue how to do this.

OpenStudy (mathmale):

g(x) = x^3, or (x)^3 There are 3 instances of 'x' here. Replace each instance of "x" with (x-1) (which is the function f(x).

OpenStudy (will.h):

Brilliant!

OpenStudy (mathmale):

To do part of the work for you: g( ) becomes ( )^3 Inside the first set of parentheses, write 'f(x)' Inside the 2nd set of parentheses, write x-1 remember that f(x) = x-1 Show your work, please.

OpenStudy (will.h):

Mathmale could you pm me

OpenStudy (imterribleatmath):

so gf(x) becomes x-1^3
