Question

when simplifying rational expressions, a cancellation indicates a hole on the graph of the corresponding rational function. true false

Explanation:

When simplifying rational expressions, if we cancel out a common factor in the numerator and denominator, the value that makes this common - factor zero results in a hole in the graph of the rational function. This is because the original function is undefined at that value, but the simplified function would be defined there if we didn't consider the original domain restrictions.

Answer:

True
