Given information
The function given is discontinuous at and at .
Step-by-step explanation
Step 1.
A Removable discontinuity is a point on the graph that is undefined or does not fit the rest of the graph.
Jump discontinuity is when the two-sided limit doesn't exist because the one-sided limits aren't equal.
As at there is removable discontinuity, so we will draw an open circle at 3 and extend the lines both the sides till .
At , there is jump discontinuity so at open circles are drawn.
