Transformations of Functions and Graphs

The video tutorial covers transformations of exponential and logarithmic functions, using similar methods as polynomial transformations. It explains the roles of variables A, B, H, and K in these transformations, and demonstrates how to graph parent functions and apply transformations through example problems. The tutorial also guides on identifying transformations and writing transformed functions.

What is the main similarity between transforming exponential/logarithmic functions and polynomials?

• They use different formulas.

• They have different variables.

• They are unrelated.

• They use the same transformation formula.

What does the 'a' value represent in the transformation formula?

• Vertical stretch or compression

• Horizontal stretch or compression

• Translation up or down

• Translation left or right

How does the 'b' value affect the transformation?

• It causes a horizontal reflection.

• It affects the y-axis.

• It causes a vertical reflection.

• It affects the x-axis.

What is the first step in graphing a parent function?

• Sketch the graph.

• Identify the asymptotes.

• Find the y-intercept.

• Apply transformations.

How do you find the y-intercept of an exponential function?

• Set y to 1.

• Set x to 1.

• Set y to 0.

• Set x to 0.

What happens to the graph when you apply a vertical stretch by a factor of 2?

• The x-values are doubled.

• The y-values are doubled.

• The graph shifts left.

• The graph shifts right.

In the function 2^x - 4, what does the '-4' represent?

• A vertical stretch

• A downward translation

• A horizontal stretch

• An upward translation

What is the effect of a negative sign in front of a logarithmic function?

• It reflects the graph over the y-axis.

• It reflects the graph over the x-axis.

• It shifts the graph up.

• It shifts the graph down.

How do you identify the transformations in a function?

• By finding the intercepts

• By looking at the coefficients and constants

• By graphing the function

• By solving the function

What is the first step in writing a transformed function?

• Identify the parent function

• Apply the transformations

• Find the intercepts

• Graph the function
