Which of the following functions are continuous. select all that apply.

The function which are continuous are:

                Function 2 and Function 3.  (graphs attached)

We know that a function is said to be a continuous function if the limit at each of the points exist and is equal to the value of the function at that point.

Also, in the graph of a continuous function there is no break i.e. the graph is connected at all the points.

      and hence the function is not continuous.

This means that the limit at x= -1 does not exist and hence the function is not continuous.
