1. (10 points) Consider the following graph of f(x). (a) Find the values of the following: (i) f ( - 7 ) = (ii) f(11) = (b) Find the following limits or write does not exists (D.N.E): (i) lim f(x) = (ii) lim f(x)= lim f(x) = * + - 7 1-+3 x-+11 (c) Which r-values are discontinuities on the graph? Identify which are removable or non- removable
