The height of a ball Doreen tossed into the air can be modeled by the function h(x) -4.9x2 + 6x + 5, where x is the time elapsed
in seconds, and h(x) is the height in meters. The number 5 in the
function represents...
(1) the initial height of the ball
(2) the time at which the ball reaches the ground
(3) the time at which the ball was at its highest point
(4) the maximum height the ball attained when thrown in the air

Solve for x and select the correct answer
