1. Consider the function f(x) = x2. The graph of f(x) is reflected over the x-axis, shifted 5 units to the right, and 2 units down to produce g(x). What is the equation of g(x)?
A. g(x) = -(x − 5)2 − 2B. g(x) = (x − 5)2 – 2 C. g(x) = -(x + 5)2 − 2D. g(x) = (x + 5)2 – 2

2. If the vertex of a parabola is (1, 2) and the graph opens down, which of the following could represent this function?
A. f(x) = –(x + 1)2 + 2B. f(x) = –(x + 2)2 + 1C. f(x) = (x – 1)2 + 2D. f(x) = –(x – 1)2 + 2

3. Using the parent function f(x) = x2, which equation models the transformations of the graph?
A. f(x) = -2(x – 3)2 + 4B. f(x) = 2(x – 3)2 + 4C. f(x) = -2(x + 3)2 + 4D. f(x) = 2(x + 3)2 + 4
