Math Problem Statement

Bayangan fungsi f(x) = 2(3x - 5) + 1 oleh translasi (-2/3) adalah?

Solution

The problem provided in the image asks for the result of translating the function f(x)=2(3x5)+1f(x) = 2(3x - 5) + 1 by a translation vector (23)\left( \frac{-2}{3} \right).

Step-by-step explanation:

  1. Original function:
    f(x)=2(3x5)+1f(x) = 2(3x - 5) + 1 Simplifying it: f(x)=6x10+1=6x9f(x) = 6x - 10 + 1 = 6x - 9 So, the function is now f(x)=6x9f(x) = 6x - 9.

  2. Translation vector:
    The translation vector (23)\left( \frac{-2}{3} \right) suggests a translation in both the xx-direction and the yy-direction. The exact form is unclear from the image, but generally, a translation applies changes to both the xx and yy coordinates.

  3. Impact on the function: A translation affects the function based on how the vector modifies xx and yy. If we are translating the input xx-value by 23\frac{-2}{3}, this affects xx in the following way:

    f(x)f(x) is transformed to f(x23)=f(x+23)f\left( x - \frac{-2}{3} \right) = f\left( x + \frac{2}{3} \right).

  4. Applying the translation: We substitute x+23x + \frac{2}{3} into the function: f(x+23)=6(x+23)9f\left( x + \frac{2}{3} \right) = 6\left( x + \frac{2}{3} \right) - 9 Simplifying the expression: =6x+49=6x5= 6x + 4 - 9 = 6x - 5

So, after the translation, the new function becomes f(x)=6x5f(x) = 6x - 5.

Final Answer:

The image of the function f(x)f(x) under the translation by (23)\left( \frac{-2}{3} \right) is f(x)=6x5f(x) = 6x - 5.


Do you want further details or have any questions?

Here are some related questions to expand on the topic:

  1. How do different translations affect linear functions like this one?
  2. What happens if the translation vector affects both xx and yy?
  3. Can we apply translations to non-linear functions similarly?
  4. How does a translation in the yy-direction only affect a function?
  5. What are the general rules for translating functions geometrically?

Tip: When applying translations, be careful to adjust the input xx-value in accordance with the vector components.
