The equation for the height of a ball that is thrown is given by h = -5t? + 15t + 20 where h is the height of the ball (in feet) and t is the number of seconds after the ball is
thrown. What does the y-intercept represent in this context?
a. The y-intercept indicates that the ball is thrown up at a velocity of 5 feet per
second
b. The y-intercept indicates that the ball starts at 15 seconds.
c. The y-intercept indicates that the ball starts at 20 feet.
d. The y-intercept indicates that when the ball was re-leased at t=1, it was thrown
upward with a velocity of 15 feet per second.
