Solution
We are asked to evaluate the limit of the function
as .
Part 1: Understanding the Problem
We are trying to find . Direct substitution of into leads to an indeterminate form, because the denominator becomes 0. Therefore, we'll use a table of values to explore the behavior of the function as approaches 2 from both sides.
Part 2: Constructing a Table
We will evaluate for values of approaching 2 from both the left (values less than 2) and the right (values greater than 2). The values we will use are: 1.9, 1.99, 1.999, 2.001, 2.01, 2.1.
Let's now calculate for each value of .Here are the calculated values of for the given values of :
1.9 | -33.784 |
1.99 | -341.067 |
1.999 | -3413.860 |
2.001 | 3414.567 |
2.01 | 341.774 |
2.1 | 34.491 |
Part 3: Analyzing the Table
As approaches 2 from the left (values less than 2), becomes increasingly negative. As approaches 2 from the right (values greater than 2), becomes increasingly positive. This suggests that the function does not settle on a specific value as ; instead, the function tends toward (positive or negative) as .
Thus, we conclude:
because the left-hand limit and right-hand limit do not agree.
