Given that f(x)=−4x+8, what is the average value of f(x) over the interval [−5,−3]? (Enter your answer as an exact fraction if necessary.)

Step 1

To calculate the average by integration.

Step 2

The graph of y=-4x+8 (a straight line) is drawn between the limits -5 and -3, by connecting the points (-3,20) and (-5,28).

Step 3

The average value of y=f(x) between a and b is obtained by dividing the area bet...
