1. (a) (10 points points) Draw the graph of a single function whose domain is (-cc, 3) U (3. co) with the following properties: . f is continuous on its domain except at a = -1 where /(-1) = 0, lim,-1- f(x) = 1, and lim,--1+ f(2) =3; . lim,- -co f(x) = lime- f() =0; . the slope of the tangent line to the graph of f(@) at r = 5 is 0. (b) (5 points points) Write an expression for the function you drew in the first part
