Full solution stays hidden until you ask for it.
1. Name the graph feature.
2. Locate structural components that create that feature.
3. Identify the controlling sub-expression.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Attributing asymptote to numerator zero or intercept to denominator zero.
