A: given f(x) = x^2 + 16 - 24 and g(x) = x^2 - 5x - 17, find (f+g)(x), then find (f+g)(3)

(possible answers for (f+g)(3): 2x^2 + 11x - 41 or 2x^2 + 11x - 7)

b: given f(x) = 4x^3 - x^2 - 68x + 35 and g(x) = x^3 + 4x - 11, find (f - g)(x), then find (f - )

(possible answers for (f-): 3x^3 - x^2 - 72x + 46 or 3x^3 - x^2 -64x +24)
