For questions 7 – 8, use the following functions: f(x) = 4x + 3x g(x) = 2x – 5 7. Find (f + g)(x). 8. Find (f – g)(x).

Answer:
7) (f+g) (x) = 4^x + 5x -5
8) (f-g) (x) = 4^x + x - 5
Step-by-step explanation:
7) Find (f +g)(x)
(4^x + 3x + 2x - 5)
(4^x + 5x -5)
(f+g) (x) = 4^x + 5x -5
8) Find (f-g)(x)
(4^x + 3x - 2x - 5)
(4^x + x - 5)
(f-g) (x) = 4^x + x - 5
