- math question 3- very urgent ! -
**drwls**, Monday, December 20, 2010 at 1:47amTha average value of f is the integral of the function (over that [0,2] interval) divided by the interval width, 2.

I assume you know how to integrate the function. The value of the integral is

5/2*4 + 18 = 28 . The average value is therefre 28/2 = 14

Now find what value of x that makes

5x + 9 = 14. It is 1

That should not be a surprise. For a linear function, the average is the value in the middle of the interval.
