Chapter 14: Q. 40 (page 876)

In Problem, graph each function. Use the graph to find the indicated limit, if it exists.
$\underset{x \to 0}{l i m} f (x), f (x) = \{\begin{cases} 1 & i f x < 0 \\ - 1 & i f x > 0 \end{cases}$

Short Answer

limit of function doesn't exist

Step by step solution

Step1. Given information

The given function $\underset{x \to 0}{l i m} f (x), f (x) = \{\begin{cases} 1 & i f x < 0 \\ - 1 & i f x > 0 \end{cases}$

Step2. Calculating the limit of the given function

To find the limit we have to draw the graph of its

We know that at the limit point as x-factor is near to limit points so that time y tends to a specific value, that specific value is the value of the function at the limit point

According to the question when x is near 0

the first segment of the graph is near 1 but the second segment tends to be -1

The value of both parts of the graph is different at the same value, so on this value limit of the given function doesn't exist
