Question 1147852: Write an equation of the parabola that passes through the point (−10,48) and has x-intercepts −8 and 50. Then find the average rate of change from x=−8 to x=−5 Answer by ikleyn(52781) (Show Source):
The average rate of change of this function from x= -8 to x= -5 is
r = = .
Notice that f(-8) = 0, so the last formula simplifies to
r = .
You do the rest.
