What do a and b do to the transformations of a function

The video tutorial explains transformation functions focusing on the roles of 'a' and 'b'. It covers how 'a' affects vertical stretch and compression, and how 'b' influences horizontal stretch and compression. The tutorial uses examples to illustrate these concepts, highlighting the effects of different values of 'a' and 'b' on graphs.

What is the significance of 'a' being equal to 0 in the context of graph transformations?

Describe the transformation that occurs when 'b' is greater than 1.

How does a horizontal stretch differ from a vertical stretch in graph transformations?
