1. What patterns do you notice in the graph when the coefficients of the quadratic in the denominator are altered?
2. How does changing the coefficient 'a' in the numerator (ax + b) impact the graph of the function? Consider both positive and negative values.
3. Identify the vertical asymptotes of the function and relate them to the denominator's factors. How do they shift when you tweak 'c', 'd', and 'e'?
4. Examine the horizontal asymptote or the end behavior of the function. What happens as x approaches positive or negative infinity?
5. Can you find a set of coefficients where the graph crosses the horizontal asymptote?
6. Challenge: Create a scenario where the function has a "hole" (a removable discontinuity). What condition on the coefficients would lead to this situation?
