Answer:
Steps of finding maximum value...
Step-by-step explanation:
Differentiate the given function.
let f'(x) = 0 and find critical numbers
Then find the second derivative f''(x).
Apply those critical numbers in the second derivative.
The function f (x) is maximum when f''(x) < 0
The function f (x) is minimum when f''(x) > 0
To find the maximum and minimum value we need to
apply those x values in the original function.
