f(2) = 1/2
f(7) = 1/7
avg rate of change = (1/7 - 1/2)/(7-2)
= (-5/14)/5)
= -1/14
don't go with decimals, they are not accurate,
stay with fractions for exact answers.
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?
WROK:
y1= 1/x (put this for my y-value in my calculator
then (y1(7)-y1(2))/(7-2) which equals -.071

thank you apparently that is all I had to do=)
