Math Problem Statement
The graph of the function f(x) is given. Answer the questions about f(a), lim(x→a) f(x), and continuity at different values of a.
Solution
Let's analyze the graph of to answer the questions in the table. We are tasked with filling in the values for , , and whether is continuous at the given values of .
Step-by-step:
-
For :
- : At , the graph has a point at , so .
- : As approaches -5 from both sides, the value approaches , so .
- Continuity: Since and the limit exists and equals , the function is continuous at .
-
For :
- : At , the graph shows a hole (open circle) at , so does not exist, i.e., .
- : As approaches -2 from both sides, the value approaches , so .
- Continuity: Since does not exist, the function is not continuous at .
-
For :
- : At , the graph passes through , so .
- : As approaches 0 from both sides, the value approaches , so .
- Continuity: Since and the limit exists and equals , the function is continuous at .
