1. a)

Consider the graph of the function f below. All interesting features have integer coordinates. 10 8- 6 V 4- 2 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) = r-+11 lim f(I) = b) At which of the points r = 0;9; 11; 12 does the limit of f exist? If you have more than one answer, separate them with a semi-colon (;). C) At which of the points : = 0;9; 11; 12 is the function continuous? If you have more than one answer, separate them with a semi-colon (;).Consider the function if i 3 is continuous. n =
