Chapter 14.3, Problem 23AYU

Find $\underset{x\to 2^{-}}{\lim }f\left(x\right)$.

To determine

To find: $\underset{x\to -2^{-}}{\lim }f\left(x\right)$.

Answer to Problem 23AYU

1

Explanation of Solution

Given:

Calculation:

Since $f\left(x\right)$ approaches to $+1$, as $x$ approaches to $-2$ from the left hand side; therefore $\underset{x\to -2^{-}}{\lim }f\left(x\right)=+1$.
