Which statements are true about the graph of the function h(x) = –5x2 + 60x – 200? Select three options.

Answers:
The graph of h(x) will not intersect the graph of the parent function, f(x) = x2.
The vertex of the graph is at (6, –20).
The parabola has a maximum.

Which function has a vertex on the y-axis?
Answer:f(x) = (x – 2)(x + 2)

Answer: x = 10

Giselle graphs the function f(x) = x2. Robin graphs the function g(x) = –x2. How does Robin’s graph relate to Giselle’s?
Answer: Robin’s graph is a reflection of Giselle’s graph over the x-axis.
