To find a maximum that’s relative
You have to walk these steps defined in full.
Remember, relative extrema live
(Or are) there at numbers critical,
And they should be continuous at “c”.
Monotonicity, after the lull,
(In here there is no measure of degree)
Just find the plus or minus interval
By choosing terms inside each chosen span.
From here you solve the “f’(x)” by use
Of chosen terms. A part whose graphed slope ran
Upwards-down is maximum, perhaps obtuse.
These things are all you have to keep in mind
When finding functions, some numbered or lined.
