Use limits to determine if f ( xx ) = is continuous at x = 1. x-1" lim f(x) = limf(x) = f(1) so the function is continuous at x = 1. cannot determine using limits lim f(x) = limf(x) # f(1) so the function is not continuous at x = 1. x-1 O lim f(x) * lim f(x) so the function is not continuous at x = 1. x- 1 17 18 19 20 21 22 MacBook Air 44 20 F8 F9 F3 000 F4 F5 F6 F7 & LA % 4 6 8 9 5 D T Y U
