Calculate the average rate of change of the given function over the given interval. Where appropriate, specify the units of measurement.
f(x) = 1/x;[2, 7]
I used the f(b)-f(a)/b-a and I got -.071 and it said I was wrong could you please help me find my error?
y1= 1/x (put this for my y-value in my calculator
then (y1(7)-y1(2))/(7-2) which equals -.071
