B.

The limit does not exist.

Solution

It looks like you're dealing with a right-hand limit problem:

limx2+f(x)\lim_{x \to 2^+} f(x)

To determine whether the limit exists and find its value, you'll need information about the function f(x)f(x).

  • If f(x)f(x) approaches a specific finite value as xx approaches 2 from the right, then the limit equals that value.
  • If f(x)f(x) increases or decreases without bound or behaves erratically, the limit does not exist.

Could you provide the function definition or a graph of f(x)f(x)? That way, I can help determine the correct answer.
