Solution

To solve this problem, we need to determine the transformation that takes the function f(x)=x+42f(x) = \sqrt{x+4} - 2 to g(x)g(x). The transformation could involve shifts, stretches, compressions, or reflections. Since the graph of g(x)g(x) is a transformation of f(x)f(x), we should investigate the graph of both functions to identify what changes have been made.

However, since you mentioned doing 10 problems and provided a list format (1 to 9), it seems you are asking for multiple questions or examples of similar transformations.

For this first example:

Step-by-Step Process:

  1. Analyze the function f(x)f(x): f(x)=x+42f(x) = \sqrt{x+4} - 2

    • This is the graph of y=xy = \sqrt{x}, but shifted left by 4 units (due to x+4x + 4) and down by 2 units (due to the 2-2).
  2. Analyze the graph of g(x)g(x):

    • Since the graph of g(x)g(x) is a transformation of f(x)f(x), we can assume different types of transformations, like horizontal or vertical shifts, stretches, or reflections.
    • To find g(x)g(x), we need to figure out what changes occurred based on the graph. If the graph of g(x)g(x) is a shift of f(x)f(x) or any other transformation, we will modify the expression for f(x)f(x) accordingly.

Without a detailed description or visual of the graph, I can provide common transformations. Here are some transformations we might encounter:


Example Transformations:

  1. Vertical Shift: If g(x)g(x) is a vertical shift of f(x)f(x) by 3 units up: g(x)=x+42+3=x+4+1g(x) = \sqrt{x+4} - 2 + 3 = \sqrt{x+4} + 1

  2. Horizontal Shift: If g(x)g(x) is a horizontal shift of f(x)f(x) by 5 units to the right: g(x)=x1+42=x+32g(x) = \sqrt{x-1+4} - 2 = \sqrt{x+3} - 2

  3. Reflection: If g(x)g(x) is a reflection of f(x)f(x) across the y-axis: g(x)=x+42g(x) = \sqrt{-x+4} - 2

  4. Vertical Stretch: If g(x)g(x) is a vertical stretch by a factor of 2: g(x)=2(x+42)=2x+44g(x) = 2(\sqrt{x+4} - 2) = 2\sqrt{x+4} - 4

  5. Horizontal Stretch: If g(x)g(x) is a horizontal stretch by a factor of 2: g(x)=x+422g(x) = \sqrt{\frac{x+4}{2}} - 2

  6. Reflection over x-axis: If g(x)g(x) is a reflection over the x-axis: g(x)=x+4+2g(x) = -\sqrt{x+4} + 2


To clarify this transformation and answer more questions, I'd need to know what specific transformation happened to f(x)f(x) to get g(x)g(x). Would you like to provide additional details or clarify how the graph of g(x)g(x) looks in relation to f(x)f(x)?


Here are 5 related questions to deepen your understanding:

  1. How does the function y=xy = \sqrt{x} behave with horizontal and vertical shifts?
  2. What happens to the graph of a square root function if it's reflected over the x-axis?
  3. How does a horizontal stretch affect the equation of a square root function?
  4. How do vertical shifts affect the equation of a square root function?
  5. What is the general effect of a vertical stretch or compression on the graph of a function?

Tip:

Whenever you deal with transformations of functions, remember that horizontal shifts affect the input xx inside the function, while vertical shifts affect the output of the function. Keep these principles in mind to help identify the transformation.
