Transformations of Exponential Functions

The video tutorial explores the transformation of exponential functions, focusing on the graph of f(x) = b^x and its transformation to g(x) = b^(2x). It explains that g(x) is horizontally compressed by a factor of half, meaning the x-values are halved for the same y-values. The tutorial demonstrates this transformation by showing how the point (6,8) on f(x) transforms to (3,8) on g(x), concluding with the correct answer to a related question.

What is the initial function mentioned in the transformation problem?

• f(x) = b^(2x)

• f(x) = b^x

• G(x) = b^(3x)

• G(x) = b^x

Which point lies on the graph of the initial function f(x) = b^x?

• (8, 3)

• (8, 6)

• (6, 8)

• (3, 8)

What is the transformed function G(x) in the problem?

• G(x) = b^(2x)

• G(x) = b^x

• G(x) = b^(3x)

• G(x) = b^(x/2)
