Question

I already did A and B. I know how to solve Part C but I don't know what to factor in for x.
Use the functions f(x) = 5x − 12 and g(x) = 11x + 2 to complete the function operations listed below.
Part A: Find (f + g)(x). Show your work. (3 points)
Part B: Find (f ⋅ g)(x). Show your work. (3 points)
Part C: Find f[g(x)]. Show your work. (4 points)

Answer 1

f(g(x)) means take g(x) and substitute it into f(x) in place of x

so

f[g(x)] = 5(11x + 2) -12

now simplify the answer

Answer 2

@campbell_st ah okay you simplify that to get your answer? Thanks so much.

Answer 3

that's correct
