which of the functions graphed below has a removable discontinuity?
Answer
Brief Explanations:
A removable discontinuity appears as a hollow point on the graph, where the limit exists but the function is undefined or has a different value at that point. Analyze the graph for such a feature.
Answer:
The function with a hollow circle (indicating a missing point where the limit exists) has a removable discontinuity.
