1.Suppose C and D represent two different school populations where C > D and C and D must be greater than 0. Which of the following expressions is the largest? Explain why. Show all work necessary.

A: (C + D)2

B: 2(C + D)

C: C2+ D2

D: C2? D2

2.Two students, Carlos and Sophie, factored the trinomial -4x2? 10x + 6. Sophie factored it as -2(2x ? 1)(x + 3) and Carlos factored it as (x + 3)( -4x + 2). Indicate which student factored the trinomial completely and which student did not, and explain why. (10 points)

3.Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).

f(x) = -2(x-4)²+2

g(x) = 5x²-10x+7

h(x) =
