Move to Numerator:
Convert the negative exponent to a positive exponent by moving

Question
Let
h

=
log
2
(
x
)
h(x)=\log _{2}(x)
h
(
x
)
=
lo
g

.
\newline
Can we use the mean value theorem to say the equation
h
′
(
x
)
=
1
h^{\prime}(x)=1
h

(
x
)
=
1
has a solution where

?
\newline
Choose

answer:
\newline
(A) No, since the function is not differentiable on that interval.
\newline
(B) No, since the average rate of change of
