Can someone provide some assistance please?
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)

Best ResponseYou've already chosen the best response.0I believe that for the first part that you're supposed to add the two equations, but the part about part A that confuses me is /how/ do you add them?

Best ResponseYou've already chosen the best response.0yes for part A you add. \[(f+g)(x)=f(x)+g(x)=5x12+11x+2\]

Best ResponseYou've already chosen the best response.0you'd add the terms with x's together and the constant terms, so (5x + 11x) + (12 + 2) Do each grouping separately

Best ResponseYou've already chosen the best response.0yeah. For B you have to use FOIL \[(5x12)(11x+2)\]

Best ResponseYou've already chosen the best response.0For C, they want f(g(x)), so you substitute g(x) for the x in f(x)dw:1440209471420:dw

Best ResponseYou've already chosen the best response.0I got 55x  2 Did you start with 5(11x + 2)  12

Best ResponseYou've already chosen the best response.0Yes, I thought when you added positive 2 to negative 12 it would end up being negative 10, or am I doing something wrong?

Best ResponseYou've already chosen the best response.05(11x + 2)  12 Distribute 5 55x + 10  12 55x  2
