A ball is thrown straight up into the air. The relationship between the height of the ball and the time since it was thrown is modeled by the function:
f(x) = -3x2 – 12x + 7
where f(x) is the height of the ball after x seconds. The function that reveals the maximum height is:
a. F(x) = 2(x+3)2 + 19
b. F(x) = -3(x + 2)2 + 19
c. F(x) = -3(x - 2)2 + 19
d. F(x) = -3(x+2)2 – 29
What is b?
