Direction: Solve the following operations on functions, with solutions.

A. Given the following:

m(x) = x² + 11x + 18

r(x) = 7x + 63

2 b(x) = -13x² + 39x

s(x) = x²-9

Find the:

1. s(x) -m(x)

2. r(x)s(x)

s(x) 3. b(x)

4. b(x) + m(x)

m(x) 5. r(x)

6. b(x)s(x)

7. m(x)-b(x)

Given: m(x) = x² + 11x + 18 r(x) = 7x + 632 b(x) = -13x² + 39x s(x) = x² - 91. s(x) - m(x) = (x² - 9) - (x² + 11x + 18) = -11x - 272. r(x)·s(x) = (7x + 632)(x² - 9) = 7x³ - 63x + 632x² - 56883. b(x) = -13x² + 39x4. b(x) + m(x) = (-13x² + 39x) + (x² + 11x + 18) = -12x² + 50x + 185. r(x) = 7x + 6326. b(x)·s(x) = (-13x² + 39x)(x² - 9) = -13x⁴ + 39x³ + 117x² - 351x7. m(x) - b(x) = (x² + 11x + 18) - (-13x² + 39x) = 14x² - 28x + 18
