Graph Transformations and Reflections

The video tutorial explains how to transform the graph of f(x) = 2^x through vertical and horizontal shifts, as well as reflections across the x-axis and y-axis. It covers the mathematical principles behind these transformations and demonstrates them using a graphing calculator. The tutorial provides a comprehensive understanding of how to manipulate graphs using algebraic expressions.

What is the effect of adding a positive constant to a function f(x)?

• Shifts the graph to the right

• Shifts the graph downwards

• Shifts the graph to the left

• Shifts the graph upwards

If f(x) is shifted down by 2 units, which of the following represents the new function?

• f(x) - 2

• f(x - 2)

• f(x) + 2

• f(x + 2)

What happens to the graph of f(x) when you replace x with x - 4?

• The graph shifts 4 units down

• The graph shifts 4 units up

• The graph shifts 4 units to the right

• The graph shifts 4 units to the left
