Practice for Quiz 2 (Sections 1.1, 1.2) 1. Given the graphs of f (x) below, find the following: a. lim f (x) = * - - 4 - lim f (x) = lim f (x) = X - - 4+ lim f (x) = x -5+ lim f(x) = * - - 4' lim f (x) = x-5 f ( -4) = f (5) = For what points is f(x) discontinuous? b. lim f(x) = lim f(x) = x - - 6 lim f (x) = -+2 lim f (x) = * - - 6+ * - 3 + lim f(x) = lim f (x) = -10 - 8 - 6_ 1 x - - 6' X-3' f ( - 6) = f (3) =. lim_f(x) = lim f(x) = lim f (x) = lim f(x) = X-7+ For what values of x is the above function discontinuous? lim f(x) = lim f (x) = x - -1 X -7 1 f ( -1) = f (7 ) = 2. Is the function f (x) = 3x - 5 for x S 2 "l x+ 1 for x > 2 continuous at the point x = 2? (show your work or explain)
