Relative Extrema
Relative Maximum: An output-value higher than the
output-values immediately neighboring it
Relative Minimum: An output-value lower than the output-values immediately neighboring it
Some things:
We can still use the word "extrema" to group these together. A question may say "Find all relative extrema"
Sometimes we use the word "local" instead of "relative"
A function can have many relative extrema, but it can only have at most one absolute max and at most one absolute min.
Remember, if the question just says "maximum" or "minimum," it means absolute, not relative.
