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.
