Question

Define left-hand limit.

Answer 1

Left-hand limit.

The left-hand limit of a function is the value of the function that approaches when the variable approaches its limit from the left.

Mathematically it can be written as:

$$\begin{gathered} \underset{\mathrm{x}\to {\mathrm{a}}^{-}}{\lim }f\left(x\right)=m \\ \Rightarrow \underset{h\to 0}{\lim }f\left(a-h\right)=m \end{gathered}$$
