.

You should take the difference of the function's values at the endpoints and divide it by the distance between the endpoints


    the average rate of change between x = 4 and x = 9  is  %28sqrt%289%2B1%29-sqrt%284%2B1%29%29%2F%289-4%29 = %28sqrt%2810%29-sqrt%285%29%29%2F5.


At this point, use your calculator.

Given f(x) = √x + 1, find the average rate of change between x = 4 and x = 9.
Answer depends on whether it's matrix%281%2C3%2C+sqrt%28x%29+%2B+1%2C+or%2C+sqrt%28x+%2B+1%29%29.

You NEED to specify where the radical ends!!
