Determine the average rate of change of f(x)=1/(x^2 -x) over the

interval 2 is less then or equal to x and 3 is greater or equal to x.

3 answers

average rate of change= f(3)-f(2) / (3-2)= 1/6-1/2=-1/3
all those words!! Why not just

2 <= x <= 3

or even better,

[2,3]
thanks that's a better way to write it
