9. The path of a freestyle skier's reverse somersault can be illustrated by the graph of the function h= -51° +10t +3, where h is the height, in meters above the ground and t is the time, in
seconds, after the skier leaves the ski jump.
a) Rough sketch the graph of the skier's height vs time
(include the y-intercept point)
b) What is the height of the skier at 1.5 seconds?
c) Convert the equation to "Vertex Form"

The skier's maximum height occurs at___
when the time is
?

d) When does the skier make contact with the ground?
