This is an exercise on the definition of continuity

A function f is continuous on a point x 0 if

For all ε>0, there exists a δ>0, such that ∣x−x 0∣<δ implies ∣f(x)−f(x 0)∣<ε.
Given a concret function (who is continuous), a x 0 and a ε>0, you have to find a δ>0 which verifies the above condition. And you will be noted according to this δ: more it is close to the best possible value, better will be your note.
