The function p(x) = 6x2 + 48x written in vertex form is p(x) = 6(x + 4)2 – 96. Which statements are true about the graph of p? Check all that apply. The axis of symmetry is the line x = –4.The graph is narrower than the graph of f(x) = x2.The parabola has a maximum.The parabola opens down.The value of k is –96, so there is a vertical shift down 96 units.
Answer
A
The axis of symmetry is the line x = –4.
B
The graph is narrower than the graph of f(x) = x2.
C
The parabola has a maximum.
D
The parabola opens down.
E
The value of k is –96, so there is a vertical shift down 96 units.
