Exploring Transformations of Functions

The video tutorial introduces transformations of functions, focusing on the square root function. It covers vertical and horizontal shifts, reflections over the x and y axes, and vertical stretches and compressions. The tutorial uses examples to illustrate how these transformations affect the graph of a function, providing a comprehensive understanding of function transformations.

What is the parent function discussed in the video?

• y = 1/x

• y = sqrt(x)

• y = |x|

• y = x^2
