You can do this in two ways: using your imagination, or the mathematical way.
Explanation:
The first way is:
In this case
For every other value
There is no maximum, because whatever value
The mathematical way is to define the derivative of the function and set it to zero:
And then you have to define whether this is a max or min situation by taking the second derivative
