**What is the y-value of a hole called?**<\/p>\n

In mathematics and graphing, a hole refers to a point on a graph where there is a missing value. When discussing graphing functions, the y-value of a hole is called the *removable discontinuity*.<\/p>\n

A removable discontinuity occurs when a function has a hole at a certain x-value, but the function still retains its limit as it approaches that point. In other words, the function can be made continuous at the hole by simply assigning a value to the missing point.<\/p>\n

To understand this concept better, let’s delve into the characteristics of a hole on a graph and explore why it is called a removable discontinuity.<\/p>\n

**Characteristics of a hole**
\n– A hole appears as an empty space or gap on a graph, typically represented by an open circle (\u25cb).
\n– It is a singular point, differing from the rest of the graph in terms of its continuity.
\n– The x-value at which the hole is located is crucial for identifying it on the graph.
\n– Though the hole does not have a specific y-value assigned to it, the function leading to the hole has a limit value.<\/p>\n

**Explaining a removable discontinuity**
\nWhen observing a function that contains a hole, there is a circumstance where the graph seems momentarily interrupted. However, this break in continuity doesn’t mean the function diverges into infinity or approaches an undefined value at that point.<\/p>\n

In fact, at the x-value of the hole, the function still possesses a definite limit and can be extended by assigning the missing y-value. By filling in this missing point, the graph becomes continuous, transforming the hole into a connected point.<\/p>\n
