Understanding Transformations of the Square Root Function

The video tutorial explains how to determine the equation of a transformed square root function. It covers the reflection across the x-axis, translation by analyzing corresponding points, and the absence of vertical stretch. The function is shifted right by one unit and up by two units. The tutorial demonstrates how to verify the equation using a graphing calculator, ensuring it matches the given function and contains specific points.

What is the final equation of the blue square root function?

• g(x) = √(x + 1) + 2

• g(x) = -√(x + 1) + 2

• g(x) = √(x - 1) - 2

• g(x) = -√(x - 1) + 2
