Given the functions m(x) = 4x − 11 and n(x) = x − 10, solve m[n(x)] and select the correct answer below. (2 points)
Citrus2011 [14]
For this case what we must do is a composition of functions which will be given by:
 m (x) = 4x - 11
 n (x) = x - 10
 We have then:
 m [n (x)] = 4 (x - 10) - 11
 Rewriting the function:
 m [n (x)] = 4x - 40 - 11
 m [n (x)] = 4x - 51
 Answer:
 a. m [n (x)] = 4x - 51

Greatest common factor is 6. If you use the distributive property then the answer would be 6(4) + 6(6) or 6(4+6). Then you distribute the 6 to each digit and should get 24+36.
