Solution

To determine the translation of the function f(x)=3x+1 f(x) = 3x + 1 that results in the function g(x) g(x) , we need to identify the typically understood translations involved with function transformations.

Step 1: Understand the Function Transformations

Functions can be translated horizontally and vertically. Here’s a brief overview of how that works:

  • Vertical Translation: Adding or subtracting a constant to the function. If f(x) f(x) is translated upwards by k k units, then g(x)=f(x)+k g(x) = f(x) + k . If translated downwards, g(x)=f(x)k g(x) = f(x) - k .
  • Horizontal Translation: Adding or subtracting a constant inside the function. If f(x) f(x) is translated to the right by h h units, then g(x)=f(xh) g(x) = f(x - h) . If translated to the left, g(x)=f(x+h) g(x) = f(x + h) .

Step 2: Analyze the Functions

Given:

  • f(x)=3x+1 f(x) = 3x + 1

We need to find:

  • The translation units for g(x) g(x) .

Step 3: Identify the Translation

Without the specific graph of g(x) g(x) , I cannot provide the exact translation. However, you typically look for shifts either horizontally left or right or vertically up or down compared to f(x) f(x) .

Step 4: General Form of g(x)

If we denote the vertical shift k k and horizontal shift h h , the function g(x) g(x) could generally be represented as:

  • Horizontal shift: g(x)=3(xh)+1 g(x) = 3(x - h) + 1 (translate right by h h ).
  • Vertical shift: g(x)=3x+1+k g(x) = 3x + 1 + k (translate vertical by k k ).

Final Answer

To obtain g(x) g(x) , you need to know the specific shifts h h and k k . The equation can be expressed as: g(x)=3(xh)+(1+k) g(x) = 3(x - h) + (1 + k) In this equation, replace h h and k k with their respective values based on the graph of g(x) g(x) .
