Transcribed Image Text:Unumpics U allu ) Slart oh Page 878. The level of detail should be the steps of the
nation WITH the explanation shown in blue beside it.
1) Recall that it takes 2 points (x,y) to create the equation of a line. It turns out that it takes 3
points to create the equation for a parabola. You throw a ball straight up from a rooftop. The
ball misses the rooftop on its way down and eventually strikes the ground. A mathematical
model can be used to describe the relationship for the ball, above the ground, y, after x seconds.
Consider the following data:
X, seconds after the ball is thrown
Y, ball's height, in feet, above the ground
