Math Problem Statement
Solution
We are given the function:
and asked to find for what value of the function has a critical point, and express the result in terms of .
Steps to Solve:
-
Critical points occur where the first derivative of the function equals zero.
We need to compute .
-
Derivative of the given function:
- The first term, , will be differentiated using the chain rule.
- The second term, , is linear, and its derivative is straightforward.
For the first term:
For the second term:
Thus, the derivative of is:
-
Set the derivative equal to zero to find critical points:
-
Solve for : Since is always positive, it follows that the sign of must match the sign of . Dividing both sides by , we get:
Thus, the critical points are determined by the above equation. We cannot explicitly solve this for without further information about , but this equation provides the implicit relationship between and .
