The transformation is a horizontal by a factor of .

Answer 1

To analyze the transformation from \( f(x) = \sqrt{x - 3} \) to \( h(x) = 2\sqrt{x - 3} \), let's break down the transformations step by step:

1. Vertical Stretch/Compression: The function \( h(x) = 2\sqrt{x - 3} \) can be seen as a vertical stretch of the function \( f(x) \) by a factor of 2. This is because the output of the function is multiplied by 2, which stretches the graph away from the x-axis.

2. Horizontal Transformation: The term \( x - 3 \) inside the square root indicates a horizontal shift. Specifically, the graph of \( f(x) \) has been shifted to the right by 3 units. This transformation applies to both \( f(x) \) and \( h(x) \) and is not changed in \( h(x) \).

We can summarze the transformations as follows:

• Vertical Transformation:

  • The vertical stretch factor is 2.
  • So, for the first response (vertical transformation), we enter 1 (for stretch) and then enter the factor which is 2.

• Horizontal Transformation:

  • The function has been shifted right by 3 units.
  • Therefore, the factor for the horizontal transformation is 3.

So the final responses would be:

1. Stretch: 1
2. Factor: 3

In summary, the transformations are:

• A vertical stretch by a factor of 2, resulting in the number 1 for stretch and 2 for the factor, and
• A horizontal shift to the right by a factor of 3.
