Question

In the preivous activity you used a table of coordinates to determine that the baseball Billy hit followed a nonlinear path.I’m this activity you will use a graphical means to make the same determination

This equation represents the path of the ball that billy
Y=-1/300 x2 +x+3

Answer 1

Part a: Answer is 1/2

78-3/1500 = 75/150

= 1/2

Part b: Answer is -1/2

3-78/300-150

=-75/150

= -1/2

Part c: No, the two rates aren't the same,

because one is positive and the other is

negative.

Part d: The rate of change of the function

determined by using the two pairs of

coordinates is not the same. So, the

function modeling the movement of the

ball is a nonlinear function
