Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

Identify the hole in the function $$f(x) = \frac{(x-3)(x+2)}{(x-3)(x+1)}$$.

💡 Hint: Look for the factor that cancels in both numerator and denominator.

Question 2

Easy

For the function $$g(x) = \frac{(x-1)(x+2)}{(x-1)(x-4)}$$, what is the hole?

💡 Hint: Identify the canceled factor.

Challenge Problems

Push your limits with challenges.

Question 1

Graph the function $$f(x) = \frac{(x-1)(x+2)}{(x-1)(x^2)}$$. Identify both the holes and the behavior as you approach.

💡 Hint: Don't forget to check both numerator and denominator for cancellation.

Question 2

Consider the function $$g(x) = \frac{x^3 - 6x^2 + 9x}{x^2 - 4}$$. Determine the holes and provide a detailed analysis of the graph.

💡 Hint: Factor thoroughly and analyze each component.
