Consider the following function: f ( x ) = (x + 1) 2 if x3 Determine if f(x) is continuous at x = 3 . If not, select the option with the correct reasoning as to why not. O Not continuous at x =3 because lim f(x) does not exist Continuous at x = 3 O Not continuous at x =3 because f(3) is undefined O Not continuous at x =3 because lim f(x) #f(3)
