Given information
The function is discontinuous at -1 and 4, but continuous from the left at -1 and from the right at 4.
Step-by-step explanation
Step 1.
The function is discontinuous at -1 and 4, but continuous from the left at -1 and from the right at 4.
At -1, the function is left continuous so draw a closed circle and extend to the left. In the interval (-1,4) the function is continuous except at the end points so represent the end points by open circles. At 4, the function is right continuous so we have to draw a closed circle and extend the line to the right.
