Consider the graph of the function f below. All interesting features have integer coordinates. 101 y 8 6- T CN 2 0 5 10 X 15 20 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) = x 0- lim f(x) = x+0+ lim f(x) = x 3 lim f(x) = x+3+ BB b) At which of the points x = 0; 1; 3; 4 does the limit of f exist? Answer: FORMATTING: If you have more than one answer, separate them with a semi-colon (;). c) At which of the points x = 0; 1; 3; 4 is the function continuous? Answer: FORMATTING: If you have more than one answer, separate them with a semi-colon (;).
