Question

In Problems 17–22, use the graph shown to determine if the limit exists. If it does, find its value.

$18.\underset{x\to 4}{\lim }f\left(x\right)$

Short answer

The value is$\underset{x\to 4}{\lim }f\left(x\right)=-3$.

Step-by-step solution

Step 1. Given information.

A graph is given as follows where we need to find$\underset{x\to 4}{\lim }f\left(x\right)$

Step 2. Finding the limit.

To find the limit of the function asx approaches to 4 of f(x).

From the graph, the value of x approaches to 4, the value of the function gets closer to $-3$.

So,$\underset{x\to 4}{\lim }f\left(x\right)=-3$.
