Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
Therefore, given a function, f(x), over an interval (2, 9), the average rate of change of the function can be found using the expression
The first equation is
The second equation is
If you sum the two equations you'll cancel y:
And since the sum must be 11, we have y=9.
