Elasticity Consider the following.

Demand Function Quantity Demanded

$p=\frac{700}{x+4},x=22$

Find the price elasticity $of$ demand for the demand function $at$ the indicated $x-$value.

$Is$ the demand elastic, inelastic, $orof$ unit elasticity $at$ the indicated $x-$value?

$a.$ The demand $is$ elastic $at$ this $x-$value.

$b.$ The demand $is$ inelastic $at$ this $x-$value.

$c.$ The demand $isof$ unit elasticity $at$ this $x-$value.

Use a graphing utility $to$ graph the revenue function.

Identify the intervals $of$ elasticity and inelasticity. $(Enter$ your answers using interval notation. $Ifan$ answer does not exist, enter DNE.$)$
