You are given the function $R(p)=3000p*e^{-0\mathrm{.}04p}(Revenue$ based $onan$

exponential demand$)$

Answer the following three results:

$a{R}^{\text{'}}(p)$

$bR(p)is$ decreasing

$(or$ state this cannot $be$ found$).$ You may use inequality $or$ interval notation.

Any numbers must $be$ accurate $to$ two decimal places.

$c{R}^{\text{'}}(p)is$ negative $(or$

state this cannot $be$ found$).$ You may use inequality $or$ interval notation.

Any numbers must $be$ accurate $to$ two decimal places.
