Correctly show the order of operations that transforms f(x)+3^x to -f(3x-2)+1

1 answer

To transform \( f(x) + 3^x \) into \(-f(3x - 2) + 1\), we can break down this transformation step by step using the order of operations and the appropriate function manipulations.

  1. Starting Expression: \[ f(x) + 3^x \]

  2. Substituting into the Function: To relate it to \( -f(3x - 2) \), we need to investigate how we can manipulate \( f(x) \). The manipulation suggests we might be transforming the input of the function \( f \).

  3. Applying a Transformation: Let's consider the term \( f(3x - 2) \). We replace \( f(x) \) by its input form: \[ f(x) \rightarrow f(3x - 2) \]

  4. Negating the Function: We now need to apply the negative sign and add \( 1 \): \[ -f(3x - 2) + 1 \]

  5. Consistency Check: To ensure that the transformation is valid within the functions we are dealing with, notice:

    • The function is transformed from \( f(x) \) to \( f(3x - 2) \).
    • The output is negated, indicating a reflection about the horizontal axis.
    • Finally, \( +1 \) is added, moving the entire function upwards by 1 unit.

Hence, the transformation from \( f(x) + 3^x \) to \( -f(3x - 2) + 1 \) can be made clear with the steps involving function transformations and basic operations.

Summary of Steps:

  1. Start with \( f(x) + 3^x \).
  2. Consider the transformation \( f(x) \to f(3x - 2) \).
  3. Apply negation to the function: \( -f(3x - 2) \).
  4. Add 1 to the result.

Therefore, the ordered operations result in: \[ f(x) + 3^x \rightarrow -f(3x - 2) + 1 \]
