Multi-Step A gymnast who can stretch her arms up to reach 6 feet
jumps straight up on a trampoline. The
height of her feet above the trampoline
can be modeled by the equation
h= -16x2 + 12x, where x is the time in
seconds after her jump. Do the gymnast's
hands reach a height of 10 feet above
the trampoline? Use the discriminant to
explain. (Hint: Let h = 10 – 6, or 4.)

Use composition to determine if (x) or h(x) is the inverse of f(x) for the limited domain x2-1.
