Question 5. [20 marks] A function f(x) is given by its graph in the picture below. This function is continuous at x = 5, and f(5) = 4.5. By definition, this means that for any > 0 there exists > 0 such that, for all x: |x - 5| < , |f(x) - 4.5| < . We choose = 0.5. Suggest at least two values of \delta that satisfy this definition.
