Question 1: What is the horizontal line that a graph approaches but never touches called?
Topic: Functions and Their Properties
- tangent
- intercept
- boundary
- asymptote (Correct Answer)
Explanation
When graphing data like population growth or radioactive decay, you'll often see curves that level off toward a horizontal line they never quite reach. This horizontal line is called an **asymptote**. The graph gets infinitely close but mathematically never touches or crosses this boundary line. Remember: asymptote sounds like "approach" - the graph approaches but doesn't meet.
