Effects of Multiplying Functions

The video tutorial explores stretching and shrinking transformations of functions. It explains how multiplying a function by a number affects its graph, either stretching or shrinking it vertically or horizontally. The video provides examples using square root and quadratic functions, demonstrating how to graph these transformations by adjusting key points. The tutorial emphasizes understanding the effects of multiplying on the inside versus the outside of a function and how these actions impact the graph's appearance.

What is the primary method used to create stretching or shrinking transformations?

• Dividing the function by a number

• Adding a constant to the function

• Multiplying the function by a number

• Subtracting a constant from the function

What happens when you multiply a function by a number greater than one on the outside?

• It shrinks the function horizontally

• It stretches the function vertically

• It shrinks the function vertically

• It stretches the function horizontally

What is the effect of multiplying a function by a number between 0 and 1 on the outside?

• It stretches the function vertically

• It shrinks the function vertically

• It shrinks the function horizontally

• It stretches the function horizontally
