Use limits to determine if f(x) = tan () is continuous at x = 1. lim f(x) # lim f(x) so the function is not continuous at x = 1. X- 1 cannot determine using limits lim f(x) = lim.f(x) = f(1) so the function is continuous at x = 1. lim f(x) = limf(x) # f( 1) so the function is not continuous at x = 1. x-It x-17 18 19 20 MacBook Air 20 F1 F4 F6 F7 F2 F3 F5 $ % A &
