I need help finding h(t)

Question

Mr. Sheffield has built a toy rocket for his daughter. The rocket launches off the ground with an initial velocity of 200 feet per second. Window: −2≤x≤18-2≤x≤18 and −200≤y≤900-200≤y≤900 

Answer 1

The instructions or text should have given you the formula:

h(t) = v•t - 16t² where "h" is in units of feet and "t" is in units of seconds.

If you plug the equation y = 200x - 16x² into your graphing calculator and set the window with:

Xmin = -2

Xmax = 18

Xscl = 1

Ymin = -200

Ymax = 900

(the rest doesn't matter)

then you will get a graph that looks like this:
