-Now, we will evaluate the second derivative at all the critical points of $f$ and apply the second derivative test to determine whether the function $f$ has a local extremum at any of those points.
+Now, we will evaluate the second derivative at all critical points of $f$ and apply the second derivative test to determine whether the function $f$ has a local extremum at any of those points. Using the value for $a$ found above,
