The table below shows the time, in seconds, and height, in feet, of a ball thrown into the air. time (s) : 0 , 1 , 2 , 3
height (ft) : 5 , 12 , 18 , 16

perform a quadratic regression for the data set, and write the equation of the quadratic model relating height, h, and time, t. round coefficient and constants to the nearest hundredth
