write a quadratic function, h(t), that shows the height, in feet, of the soccer ball, t seconds after it was kicked. Use the general equation h(t) = -16t2 + v_ot + h_o where v_o is the initial velocity and h_o is the initial height. Show how you got the x-intercepts, the vertex's as well as graph it. How long was the soccer ball in the air?

What is the length of the unknown leg in the right triangle ?

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

What is the distance from zero if a quadratic function has a line of symmetry at x=-3 and a zero at 4
