A student creates a function, h(x), to model the path of a T-shirt launched from a T-shirt cannon using a quadratic function. The
shape of the parabola is correct, but the student forgets to account
for the launcher's initial height of 4 feet.
How can the student correct the function to model the path of the
T-shirt correctly?
a) The student should replace h(x) with h(x) – 4.
b) The student should replace h(x) with h(x) + 4
c) The student should replace h(x) with h(x-4)
d) The student should replace hx) with h(x + 4)
