(1) Sketch by hand the graph of a function f that satisfies: (a) f(2) = 3 and (b)limx -+2 f (x) = 4. Is the function f(x) continuous at x = 2? Explain. (2) Sketch by hand the graph of a function f that satisfies: (a) f (1) = 2 and (b)lim.-+1+ f() = 4 and(c) limr-1-f(x) = 2. Is the function f(x) continuous from the left at x = 1? Is the function f(x) continuous at x = 1 from the right? Is the function f(x) continuous at x = 1? Explain
