F (x) = 6x2 + 2x - 7 and g (x) = 4x - 3.

a. (f+g) (x)

b. (f-g) (x)

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
