Use the functions f(x) = 4x − 5 and g(x) = 3x + 9 to complete the function operations listed below.
1 answer:
A: (f+g)(x)=f(x)+g(x) (f+g)(x)=4x-5+3x+9 (f+g)(x)=7x+4 B: (f•g)(x)=f(x)•g(x) (f•g)(x)=(4x-5)(3x+9) (f•g)(x)=12x^2-15x+36x-45 (f•g)(x)=12x^2+21x-45 C: (f○g)(x)=f(g(x)) (f○g)(x)=4(3x+9)-5 (f○g)(x)=12x+36-5 (f○g)(x)=12x+31
