Consider the function

Find the maximum of the function on the interval
.
Consider the function
Find the maximum of the function on the interval .
Notice that on the interval
, the term
is always less than or equal to
. So the function is largest at the points when
. This occurs at
and
.
Plugging in either 1 or 0 into the original function
yields the correct answer of 0.

Plugging in either 1 or 0 into the original function yields the correct answer of 0.
Compare your answer with the correct one above
The function
is such that

When you take the second derivative of the function
, you obtain

What can you conclude about the function at
?
The function is such that
When you take the second derivative of the function , you obtain
What can you conclude about the function at ?
We have a point at which
. We know from the second derivative test that if the second derivative is negative, the function has a maximum at that point. If the second derivative is positive, the function has a minimum at that point. If the second derivative is zero, the function has an inflection point at that point.
Plug in 0 into the second derivative to obtain

So the point is an inflection point.
