If f(x) = x+ 6 and g(x) = x^4, what is g(f( o a. a +x+6 b. (x+6)^4 c. x^4+6 d. x^4(x+6)

ANSWER

B.

EXPLANATION

The given functions are:

f(x)=x+6

and

We want to find

This is the composition of functions, where one function becomes the input of the second function.

We plug in x+6 into the expression for g(x) to obtain,

The correct answer is B.
