How do you graph y = 15x +75 ?

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

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

Write the equation in logarithmic form m^x=n
