<em>The last option matches the correct solution</em>
Step-by-step explanation:
<u>Equation Solving</u>
We have the following equation:
And it's required to solve it for r.
Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.
It can be done by conveniently operating on both sides as follows:
Eliminate the denominator by multiplying by 3:
Move to the other side by dividing by
:
Swapping sides to have r at the left side:
Finally, take the cubic root and leave r alone:
The last option matches the correct solution
We are asked to determine what happens to the values of 
as 
approaches 
using values of less than 
AND using values of greater than .
<span>Observe from the graph that as </span> approaches from the left or the right, the values of increase without bound.
Therefore, we know the following.
