Graphing and describing a dialation 4y = x^2

The video tutorial covers the concept of dilation in mathematics, focusing on a quadratic function. It begins with an introduction to the problem and the setup for dilation. The teacher explains the parent function, y = x^2, and its graph. The process of describing dilation is detailed, including how to isolate y and understand the effect of dilation on the graph. The tutorial concludes with graphing the dilation and discussing its impact, emphasizing the horizontal expansion and compression of the graph.

What does it mean when a function is described as being 'stretched' or 'compressed'?

Explain how to graph the new function after dilation.
