algebra (parabolas)

you throw a wad of used paper towards a wastebasket from a height of about 1.3 feet above the floor with an initial vertical velocity of 3 feet per second.

a. write and graph a function that models the height h (in feet) of the paper t seconds after it is thrown

b. if you miss the wastebasket and the paper hits the floor, how long does it take for the ball of paper to reach the floor.

c. if the ball of paper hits the rim of the wastebasket one-half foot above the ground, how long was the ball in the air?
