Given f(x) =17 -x2 what is the average rate of change in f(x) over the interval [1,5]
Artist 52 [7]
By definition <span>the average rate of change is given by:
 </span>AVR =  \frac{f(x2) - f(x1)}{x2-x1}
 <span>We have the following function:
 </span>f(x) =17 - x^2
 We evaluate the function for the given interval:
 For X = 1:
 f(1) =17 - 1^2
 f(1) =17 - 1
 f(1) =16
 For X = 5:
 f(5) =17 - 5^2
 f(5) =17 - 25
 f(5) =-8
 Then, replacing values we have:
 AVR = \frac{-8 - 16}{5-1}
 AVR = \frac{-24}{4}
 AVR = -6
 Answer:
 <span>the average rate of change in f(x) over the interval [1,5] is:
 </span>AVR = -6
