The difference quotient is a measure of the average rate of change of the function over an interval (in this case, an interval of length h). The limit of the difference quotient (i.e., the derivative) is thus the instantaneous rate of change.
This difference is denoted by $\delta$ (delta). It is known as the difference in the function result of two values. This difference is termed as difference quotient. The difference quotient is used in the derivative. Dividing function difference from the difference of point is called as the difference quotient.
