Answer:
Step-by-step explanation:
Ask yourself, what is the value of the f(x) when
   x aproaches  1    f(x) =  -3
   x aproaches  1.5   f(x) =  -3
   x aproaches  1.9   f(x) =  -3
  x aproaches  1.99   f(x) =  -3
  x aproaches  1.999999999   f(x) =  -3
    lim x--> 2 from the left = -3
using the same approach as x ---> 2 from the right
   x aproaches  5     f(x) =  4
   x aproaches  4      f(x) = 4
   x aproaches  3     f(x) =  4
  x aproaches  2.5    f(x) =  4
  x aproaches  2.001  f(x) =  4
  Â
   lim x--> 2 from the right =  4
