      Not an advanced mathematician, but I think it’s just saying that f(x-delta) between f(x + delta) is going to give a value between L - epsilon and L + epsilon.

          Imagine you have a simple function: y = 2x

          If you have two different x values (let’s say 2 and 4), there exist a y value for every number in between them.

          In this example, the y is going to be in between 4 and 8, for every x in between 2 and 4.
