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

Given the graphed function below which of the following orders pairs are found on the inverse function

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
