Explanation:

Step1: Check if $f(2)$ is defined

Look at the graph: at $x=2$, there is a filled point at $y=-4$, so $f(2)=-4$, meaning it is defined.

Step2: Check if $\lim_{x \to 2} f(x)$ exists

Observe the left-hand limit (as $x$ approaches 2 from the left, the graph approaches $y=2$) and the right-hand limit (as $x$ approaches 2 from the right, the graph approaches $y=2$). Since left and right limits are equal, $\lim_{x \to 2} f(x)=2$, so the limit exists.

Step3: Check if $\lim_{x \to 2} f(x) = f(2)$

We have $\lim_{x \to 2} f(x)=2$ and $f(2)=-4$. $2
eq -4$, so this equality does not hold.

Step4: Check continuity at $x=2$

A function is continuous at $x=a$ if $\lim_{x \to a} f(x) = f(a)$. Since this equality fails here, the function is not continuous at $x=2$.

Answer:

  • $f(2)$ is defined.
  • $\lim_{x \to 2} f(x)$ exists.
  • The function is not continuous at $x = 2$.
