Understanding Graph Shifts

The video tutorial explains how to match graphs with their corresponding functions by identifying vertical and horizontal shifts. It begins with an introduction to the parent function, f(x) = √x, and discusses how different functions are shifted up, down, left, or right. The tutorial provides a detailed review of vertical and horizontal shifts, using examples to illustrate how constants inside or outside the square root affect the direction of the shift. The video concludes with a practical application of identifying graphs based on these shifts, emphasizing the importance of recognizing shift types without relying on graphing calculators.

What is the parent function identified in the problem?

• f(x) = sqrt(x)
