Transcribed Image Text:**Limits and Continuity Worksheet**
**Objective:** Use the graph below to find the indicated limits. If a limit doesn’t exist, state DNE. If value doesn’t exist, state undefined.
### Graph Explanation
The graph shows a function \( f(x) \) plotted on a coordinate plane. The x-axis ranges approximately from -4 to 7, while the y-axis ranges approximately from -10 to 10. The function has a piecewise character, with distinct behaviors in the different intervals:
- For \( x < -3 \), the function seems to increase as x approaches \(-3\).
- Just before \( x = -3 \), the function appears to reach a high value, and then drops suddenly.
- As \( x \) progresses towards 0, the function rises again, reaches a peak at \( x = 0 \), and then declines.
- Beyond \( x = 0 \) and approaching \( x = 2 \), the function reaches a minimum.
- From \( x = 2 \) onwards, the function rises sharply again, and continues increasing beyond \( x = 5 \).
Given this detailed behavior, use the relevant sections of the graph to determine the limits as specified in the exercises.
### Exercises
(n) \(\lim_{{x \to 6^+}} f(x)\)
For this specific exercise:
- As \( x \) approaches 6 from the right, observe the behavior of \( f(x) \).
- Using the graph, determine whether \( f(x) \) approaches a specific value, increases indefinitely, decreases indefinitely, or oscillates without approaching a specific value.
**Answer Key:** Ensure to write down DNE if the limit does not exist at \( x \rightarrow 6^+ \), and Undefined if the value itself is undefined.
Remember, understanding the patterns and behaviors around the critical points on the graph is essential for accurate limit determination. Happy solving!
