Function Transformations and Limits
This page focuses on function transformations and introduces the concept of limits. It begins by explaining how various transformations affect the graph of a function, such as vertical and horizontal shifts, reflections, and stretches.
Highlight: Function transformations include vertical shifts f(x)+a, horizontal shifts f(x+a), reflections −f(x)andf(−x), and stretches (af(x) and f(ax)).
The page then introduces the intuitive notion of limits, discussing two types: direct limits and limits using algebra.
Example: For a direct limit, lim(x→5) x + 7 = 5 + 7 = 12. For a limit using algebra, lim(h→0) (3+h)2−9 / h is solved by factoring and simplifying.
These examples demonstrate how to approach different types of limit problems, providing a foundation for more advanced calculus concepts.
