Consider the graph of the function f below. All interesting features have integer coordinates. 10 8 6 y 4- 2 5 10 15 20 X a) Calculate the left and right limits of these functions at the various points specified. Write diverges if the limit does not exist. lim f(x) = lim f(x) = lim f(x) = lim f(x) = b) At which of the points x = 0; 16; 18; 19 does the limit of f exist
