Help me please with the picture above and about EQUATIONS WITH VARIABLES ON BOTH SIDES

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

Which number line represents the solution set for the inequality -1/2x> 24?
