Let F be the function below. If you are having a hard time seeing the picture clearly, click on the picture. It will expand to a larger picture on its own page so that you can Evaluate each of the following expressions. Note: Enter 'DNE' if the limit does not exist or is not defined. a) lim F(x) = lim F(x) = lim F(x) = F(-1) = I) 1 b) lim F(x) = lim F(x) = lim F(x) = F(1) = 1 1 lim F(x) = lim F(x) = F(3) = c) lim F(x) = 1 13 I 13
