Learning how to identify compression and stretches of multiple functions

The video tutorial explains the effects of multiplying values inside and outside functions, focusing on vertical and horizontal transformations. It covers the concepts of vertical stretch and compression, as well as horizontal compression, using examples. The tutorial also delves into reciprocal functions and how multiplication affects them, particularly in odd functions. The instructor emphasizes understanding the general function and the impact of multiplying by different values, providing clarity on the concepts of stretch and compression.

What type of transformation occurs when a value is multiplied outside the function?

• Reflection

• Horizontal stretch or compression

• Vertical stretch or compression

• No transformation

If the absolute value of the multiplier is greater than one and it's outside the function, what transformation occurs?

• Horizontal stretch

• Horizontal compression

• Vertical compression

• Vertical stretch

What happens when a value is multiplied inside the function and the absolute value is greater than one?

• Horizontal compression

• Vertical compression

• Vertical stretch

• Horizontal stretch

What is the result of multiplying a function by a value less than one inside the function?

• Vertical compression

• Horizontal stretch

• Vertical stretch

• Horizontal compression

In the context of reciprocal functions, what is the effect of multiplying by a fraction greater than one?

• No effect

• Vertical compression

• Horizontal stretch

• Vertical stretch

How can transformations be interpreted in odd functions?

• No transformations are possible

• Only as vertical transformations

• Both vertical and horizontal transformations are possible

• Only as horizontal transformations

When dealing with transformations, what is the significance of the absolute value of the multiplier?

• It determines the type of transformation

• It has no significance

• It only affects vertical transformations

• It only affects horizontal transformations
