Final answer:
The function f(x) = 1/x is discontinuous at x = -2 because it does not have a limit at that point.
Step-by-step explanation:
The function f(x) = 1/x is discontinuous at x = -2. A function is said to be discontinuous at a given point if it does not have a limit at that point. In this case, as x approaches -2 from the left, f(x) approaches negative infinity, while as x approaches -2 from the right, f(x) approaches positive infinity.
One way to visualize the behavior of f(x) = 1/x near x = -2 is to look at its graph. At x = -2, there is a vertical asymptote, which means the function approaches infinity as x approaches -2 from either side.
To summarize, the function f(x) = 1/x is discontinuous at x = -2 because it does not have a limit at that point.
