Math Problem Statement

Describe the transformations of the function f(x) = 2√(x - 9).

Solution

To describe the transformations of the function f(x)=2x9f(x) = 2\sqrt{x-9}, consider the following:

  1. Horizontal Shift: The expression x9\sqrt{x-9} indicates a shift to the right by 9 units.

  2. Vertical Stretch: The coefficient 2 outside the square root indicates a vertical stretch by a factor of 2.

These transformations modify the parent function x\sqrt{x}.
