1.) in the year 2005, the average cost of a car could be modeled by the equation c= -15x^2 + 20x - 3 where x is the number of years since 2005. by the year 2010 the average cost had changed, and the equation could be modeled by c= -10x^2 + 30x - 2. find the difference in average cost equation for cars between 2005 and 2010.

2.) the function p(x) = 3x^2 + 4x + 5,is dilated by the function i(x) = p(2x). write the new function i(x).

3.) make a box and whisker plot of the following data. show your work as to how you calculated the different key points on the box-and-whisker plot. 21, 25, 30, 27, 22, 23, 23, 24, 26, 28, 25, 22, 23
