Math Problem Statement

The functions f and g are graphed in the same rectangular coordinate​ system, shown to the right. If g is obtained from f through a sequence of​ transformations, find an equation for g.What is the equation for​ g?

Solution

To determine the equation of g(x)g(x) from f(x)f(x), let's analyze the transformations applied to the graph of f(x)f(x) to obtain the graph of g(x)g(x).

Given the image, f(x)f(x) is a square root function, likely f(x)=xf(x) = \sqrt{x}. The graph of g(x)g(x) is shifted upwards and possibly stretched.

Step-by-Step Analysis:

  1. Identify the basic function f(x)f(x): f(x)=xf(x) = \sqrt{x} This corresponds to the black graph in the image.

  2. Vertical shift: The blue graph g(x)g(x) appears to be a vertical translation of f(x)f(x). It has been shifted up by 4 units.

    Therefore, the equation for g(x)g(x) based on this shift is: g(x)=x+4g(x) = \sqrt{x} + 4

Thus, the equation for g(x)g(x) is: g(x)=x+4g(x) = \sqrt{x} + 4

Would you like more details on any specific part of this transformation process or have any further questions?

Related Questions:

  1. What would be the equation if g(x)g(x) was shifted 3 units down instead of up?
  2. How does a horizontal shift affect the equation of a square root function?
  3. What transformation occurs if g(x)=2xg(x) = 2\sqrt{x}?
  4. How do combined transformations (e.g., vertical shift and horizontal stretch) affect the function?
  5. If g(x)=x2+4g(x) = \sqrt{x - 2} + 4, what transformation does 2-2 represent?

Tip:

When identifying transformations, always consider how each parameter (vertical shift, horizontal shift, stretching, reflection) affects the function's graph.
