Example 2 For the function J whose graph is given, state the value of each quantity, if it exists. If it does not exist, explain why. a. lim J (x) = x- -3+ y b. lim _J (x) = x- -3 C. lim J (x) = -6 x--3 d. J(-3) = -4 e. lim J (x) = +2 lim J (x) = -8 -6 -4 -2 4 6 8 X x -0+ g. lim J (x) = X - +- 2 h. J(0) = --4 1. lim J (x) = x-5 --6 J. lim, J (x) = x-5 lim J (x) = x-5 Example 3 lif xs-1 Given: f(x) = x2 - 1if - 1
