Question
Let h(x)=log⁡2(x) h(x)=\log _{2}(x) .\newlineCan we use the mean value theorem to say the equation h′(x)=1 h^{\prime}(x)=1 has a solution where 1<x<2 1<x<2 ?\newlineChoose 11 answer:\newline(A) No, since the function is not differentiable on that interval.\newline(B) No, since the average rate of change of h h over the interval 1≤x≤2 1 \leq x \leq 2 isn't equal to 11 .\newline(C) Yes, both conditions for using the mean value theorem have been met.
