Question

Let f(x) = 3x – 42 and g(x) = 5x.

Part 1 [4 points] What is (f ◦ g)(x) ?
Part 2 [2 points] Use complete sentences to describe the method you used to solve this problem.

Answer 1

f of g(x) means you substitute g(x) into x in f(x)

So you would start with:

3(5x)-42

Go ahead and try to solve from there! :D
