Given that:
f(t) = - 16t² + 51t + 8.9
Where f(t) represents the height of the baseball in feet, and t is the number of seconds that has elapsed.
(A) find f(0)
f(0) = - 16(0)² + 51(0) + 8.9
= 0 + 0 + 8.9
f(0) = 8.900 feet
(B) Find f(3)
f(3) = - 16(3)² + 51(3) + 8.9
= -16(9) + 153 + 8.9
= -144 + 153 + 8.9
f(3) = 17.900 feet
