F(x) = 6x2 + 2x − 7 and g(x) = 4x − 3.
a. (f+g)(x)
b. (f-g)(x)
1 answer:
Answer:
a) (f+g)(x) = 6x^2 +6x -10
b) (f-g)(x) = 6x^2 -2x -4
Step-by-step explanation:
a. (f+g)(x) = f(x) +g(x) = (6x^2 +2x -7) +(4x -3)
(f+g)(x) = 6x^2 +6x -10
__
b. (f-g)(x) = f(x) -g(x) = (6x^2 +2x -7) -(4x -3)
(f-g)(x) = 6x^2 +2x -7 -4x +3
(f-g)(x) = 6x^2 -2x -4
