f(x)=-4x^2+2x-3 find the average rate of change for the points defined in the interval [1,2] is the answer 10?

OpenStudy (ranga):

No. But how did you arrive at 10? Average rate of change of f(x) over [a, b] = { f(b) - f(a) } / (b - a)

OpenStudy (anonymous):

what is the correct answer?

OpenStudy (ranga):

I will assist you if you have doubts but giving out just the answers without any work is not my preference.
