Excuse me sir, but I am concerned with solving this problem.
Okay sir, what is the problem ?
I need to sketch a function with a removable discontinuity at x = -2, an infinite discontinuity at x = 1, and a jump discontinuity at x = 3.
First you sketch the graph and draw a line and when it hits x = -2, draw a circle to indicate the point.
Now I understand, thanks.
Next, continue drawing until you hit x=1, where you must then draw lines moving closer together, but never touching, and then continue until you hit x=3, in which you either jump up or down, adding a circle at the end of one of the lines
