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 factor form of x^2-9x+14

Use the quadratic function to predict f(x) if x equals 8. f(x) = 25x2 − 28x + 585
