Pick the description of a geometric object that best matches the real world object box for a deck of card

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

Find the condition that the zeros of the polynomial f(x) = x^3+3px^2+3px+r may be in a.p.
