A removable discontinuity occurs when a function has a hole at a certain point, but the limit of the function exists at that point.
Imagine you have a cake with a missing piece in the middle. Even though there is a gap, you can still determine what the missing piece would be by looking at the surrounding parts of the cake.
Limit: The value that a function approaches as it gets arbitrarily close to a particular point.
Hole: A missing point on the graph of a function where there is an open circle indicating that it is not included in the graph.
Asymptote: A line that a curve approaches but never touches or crosses.
