Questions & Step-by-Step Solutions
What does the term 'asymptote' refer to in the context of graphing functions?
Step 1: Understand that a graph represents a function, which can show how one quantity changes in relation to another.
Step 2: Learn that an asymptote is a special type of line related to the graph of a function.
Step 3: Recognize that there are different types of asymptotes: vertical, horizontal, and oblique (slant).
Step 4: Know that a vertical asymptote occurs when the graph approaches a vertical line but never touches it, usually where the function is undefined.
Step 5: Understand that a horizontal asymptote occurs when the graph approaches a horizontal line as it goes towards infinity, indicating the value the function gets closer to.
Step 6: Realize that an oblique asymptote is a slanted line that the graph approaches as it goes to infinity, typically for certain polynomial functions.
Step 7: Conclude that asymptotes help us understand the behavior of a graph at extreme values, even if the graph never actually meets the asymptote.
