To tell whether the function has a minimum value or a maximum value, and then find the value.
Answer to Problem 17Q
The function
Explanation of Solution
Given information:
The function is,
Second derivative test:
If a function has a critical point for which
If a function has a critical point for which
Calculation:
Differentiate with respect to x,
For critical point,
Subtract 10 from both sides,
Divide by 10,
Critical point is,
Again, differentiate
Second derivative is positive at point
So, the function
For maximum value, substitute
So, the function
