Question

Is the actual minimum of a graph still considered a relative minumum?

For example, this graph has two low points. Are they both relative minimums, or is the one that is the overall minimum not considered a relative minimum?

Answer 1

See below.

Explanation:

Think that all minima are relative minima but not all minima are global minima. In the case shown, both are relative minima but only at `x = 3.219` we get a global minimum.
