Question

question 9 (1 point) when simplifying rational expressions, a cancellation indicates a hole on the graph of the corresponding rational function. true false

Explanation:

When simplifying a rational expression, if a factor cancels out (i.e., \((x - a)\) in both numerator and denominator), the value \(x=a\) makes the original function undefined (since it made the denominator zero before simplification). But after simplification, the simplified function is defined at \(x = a\). This point \(x=a\) is a hole in the graph of the original rational function.

Answer:

True
