What is a dialation for a quadratic graph

The video tutorial explains the concept of dilation in mathematics, focusing on how it affects linear and quadratic graphs. It begins with an introduction to dilation using linear graphs, explaining how multiplying by a factor changes the slope. The tutorial then explores dilation in quadratic functions, demonstrating how different factors affect the graph's shape. The effects of dilation, such as horizontal stretching and compression, are analyzed. Finally, the video covers the rules for determining dilation effects using the vertex form of a quadratic equation.
