Q. Which of the following expressions are equivalent to

\newline

\frac{J}{-k}

?

\newline

Choose all answers that apply:

\newline

A

\newline

-\frac{j}{-k}

\newline

(B)

\newline

-\frac{-j}{k}

\newline

(c) None of the above

Check option A: Check option A: $-\frac{j}{-k}$ $\newline$ Simplify: $-\frac{j}{-k} = \frac{j}{k}$
Check option B: Check option B: $\frac{-(-j)}{k}$ $\newline$ Simplify: $\frac{-(-j)}{k}$ = $\frac{j}{k}$
Check option C: Check option C: None of the above $\newline$ Since both A and B are equivalent to $(J)/(-k)$ , option C is incorrect.

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

\newline

Can we use the mean value theorem to say the equation

h^{\prime}(x)=1

has a solution where

1<x<2

\newline

1

\newline

(A) No, since the function is not differentiable on that interval.

\newline

(B) No, since the average rate of change of

h
