Graphing a quadratic with a dialation

The video tutorial explains the parent graph y = X^2 and explores the vertex form y = a(X-H)^2 + K. It discusses how the values of K, H, and a affect the graph's position and shape. The tutorial focuses on graphing y = 3X^2, demonstrating how the graph becomes horizontally compressed or vertically stretched when the absolute value of a is greater than one. The session concludes with a summary of these transformations.

How do you determine the new coordinates of points on the graph after applying transformations?

What does it mean for a graph to be horizontally compressed or vertically stretched?
