−12

−3

Option

Solve the following equation algebraically: a. 4.47 b. -3.97, 3.97 c. -10, 10 d. -4.47, 4.47 Please select the best answer from the choices provided

The graph shows the axis of symmetry for a quadratic function f(x).

f(x) = (x + 4)2

f(x) = x2 + 4

f(x) = (x – 4)2

f(x) = x2 – 4

What is the vertex of the graph of y = –x2?

(–1, 0)

(0, –1)

(0, 0)

(1, 1)

Which function has a range of {y|y ≤ 5}?

f(x) = (x – 4)2 + 5

f(x) = –(x – 4)2 + 5

f(x) = (x – 5)2 + 4

f(x) = –(x – 5)2 + 4
