Math Problem Statement

The graphs of f and g are given. Find a formula for the function g.

Solution

Let's analyze the image you provided.

From what I can see:

  1. The graph shows two functions:

    • The red line labeled g(x)g(x)
    • The blue line labeled f(x)=xf(x) = |x|, which is the standard absolute value function.
  2. The goal is to find the formula for g(x)g(x).

Observations:

  • The blue graph is f(x)=xf(x) = |x|, which represents the V-shaped absolute value function.
  • The red graph appears to be a transformation of the blue one. Specifically:
    • It has the same shape as x|x|, but it is translated vertically.

Finding the formula for g(x)g(x):

  • The red graph seems to be a vertical shift of f(x)=xf(x) = |x|.
  • Notice that the vertex of the red graph is at (0,8)(0, 8) (instead of at (0,0)(0, 0) for f(x)=xf(x) = |x|).
  • This suggests a vertical shift of 8 units upward.

Therefore, the formula for g(x)g(x) is: g(x)=x+8g(x) = |x| + 8

Would you like further details or have any questions?


Here are some related questions to expand your understanding:

  1. How do vertical shifts affect the equation of absolute value functions?
  2. What changes would result in horizontal shifts for f(x)=xf(x) = |x|?
  3. How would the equation of f(x)=xf(x) = |x| change if it were reflected across the x-axis?
  4. Can you explain how scaling (compressing/stretching) affects the absolute value function?
  5. What is the general form of transformations for the function f(x)=xf(x) = |x|?

Tip: When determining shifts and transformations of a graph, always compare the vertex and slope of key segments.
