Hello, I need help on my Mathematics 30-1 Quiz 5.1 (Pre-calculus) Questions #1-#2 and Numerical response #1

Quiz 5.1 - TS thematics 30-1 lue 9 PART A: MULTIPLE CHOICE/NUMERICAL RESPONSE This quiz includes multiple choice and numerical response questions. For multiple choice questions, select the best answer. For numerical response questions, enter the numerical values into the space provided. 1. Find the sum of f(x) and g(x) if f(x) = 2x + 3x - 4 and g(x) = x+ 3. A. 2x2 + 2x - 7 B. 2x2 + 2x - 1 C. 2x2 + 4x - 7 D. 2x2 + 4x - 1 Hint: Collect like terms. 2. Find the value of h(5), where h(x) = f(x) - 8(x), f(x) = Vx + 3, and g(x) = 2Vx-1. A. 5 - 4 B. - 15+ 2 C . 15 - 2 D. -15+ 4 Hint: Collect like terms, then substitute x = 5 into the resulting function. Numerical Response Determine the value of P(5), to the nearest tenth, where P(x) = (8 75 )(x), f(x) = 1- 2x, 1 . 8 (x) = v2x+ 3, and h(x) =x2 -2x-5. Hint: Combine the functions, then substitute the value of 5 for x
