Graph this function:
y= 5x - 18

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

Can someone answer this question? : )

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2
