Answer
Explanation:
Step1: Check if $f(2)$ is defined
The graph has a filled - in dot at $x = 2$ with $y=3$, so $f(2)=3$ and $f(2)$ is defined.
Step2: Check if $\lim_{x\rightarrow2}f(x)$ exists
As $x$ approaches 2 from the left, the function approaches the open - circle value. As $x$ approaches 2 from the right, the function approaches the same open - circle value. So $\lim_{x\rightarrow2}f(x)$ exists.
Step3: Check if $\lim_{x\rightarrow2}f(x)=f(2)$
$\lim_{x\rightarrow2}f(x)$ is the value of the open - circle and $f(2)$ is the value of the filled - in dot. They are not equal.
Step4: Check continuity
For a function to be continuous at $x = a$, $\lim_{x\rightarrow a}f(x)=f(a)$. Since $\lim_{x\rightarrow2}f(x)\neq f(2)$, the function is not continuous at $x = 2$.
Answer:
$f(2)$ is defined. $\lim_{x\rightarrow2}f(x)$ exists. The function is not continuous at $x = 2$.
