Understanding Function Translation

In mathematics, function translation is a process of shifting a function's graph up, down, left, or right. This can be achieved by adding or subtracting a constant value from the function's input or output. In this article, we will explore how to find the equation of a translated function, given the original function.

Original Function

The original function is given as $f(x) = x^2$ . This is a quadratic function that represents a parabola opening upwards.

Translated Function

The translated function is denoted as $g(x)$ . To find the equation of $g(x)$ , we need to apply the translation to the original function $f(x)$ .

Translation Rules

There are four types of translations that can be applied to a function:

Vertical Translation: Shifting the graph up or down by adding or subtracting a constant value from the function's output.
Horizontal Translation: Shifting the graph left or right by adding or subtracting a constant value from the function's input.

Vertical Translation

To apply a vertical translation, we add or subtract a constant value from the function's output. In this case, we are given a vertical translation of 6 units up.

Horizontal Translation

To apply a horizontal translation, we add or subtract a constant value from the function's input. In this case, we are given a horizontal translation of 4 units to the right.

Equation of the Translated Function

Using the translation rules, we can find the equation of the translated function $g(x)$ .

Vertical Translation: $g(x) = f(x) + 6$
Horizontal Translation: $g(x) = f(x - 4)$

Substituting the original function $f(x) = x^2$ into the equation, we get:

$g(x) = (x - 4)^2 + 6$

Answer

The equation of the translated function $g(x)$ is:

$g(x) = (x - 4)^2 + 6$

This is option A.

Conclusion

In this article, we explored how to find the equation of a translated function, given the original function. We applied the translation rules to the original function $f(x) = x^2$ and found the equation of the translated function $g(x)$ . The equation of the translated function is $g(x) = (x - 4)^2 + 6$ .

Frequently Asked Questions

In this article, we will answer some frequently asked questions about translated functions.

Q: What is a translated function?

A: A translated function is a function that has been shifted up, down, left, or right from the original function. This can be achieved by adding or subtracting a constant value from the function's input or output.

Q: How do I find the equation of a translated function?

A: To find the equation of a translated function, you need to apply the translation to the original function. This can be done by adding or subtracting a constant value from the function's input or output.

Q: What are the different types of translations?

A: There are four types of translations:

Vertical Translation: Shifting the graph up or down by adding or subtracting a constant value from the function's output.
Horizontal Translation: Shifting the graph left or right by adding or subtracting a constant value from the function's input.

Q: How do I apply a vertical translation?

A: To apply a vertical translation, you add or subtract a constant value from the function's output. For example, if you want to shift the graph 6 units up, you would add 6 to the function.

Q: How do I apply a horizontal translation?

A: To apply a horizontal translation, you add or subtract a constant value from the function's input. For example, if you want to shift the graph 4 units to the right, you would add 4 to the function's input.

Q: What is the equation of a translated function?

A: The equation of a translated function is found by applying the translation to the original function. For example, if the original function is $f(x) = x^2$ and you want to shift it 4 units to the right and 6 units up, the equation of the translated function would be $g(x) = (x - 4)^2 + 6$ .

Q: How do I determine the type of translation?

A: To determine the type of translation, you need to look at the equation of the translated function. If the constant value is added to the function's output, it is a vertical translation. If the constant value is added to the function's input, it is a horizontal translation.

Q: Can I have multiple translations?

A: Yes, you can have multiple translations. For example, you can shift the graph 4 units to the right and 6 units up, and then shift it 2 units down.

Q: How do I apply multiple translations?

A: To apply multiple translations, you need to apply each translation in the correct order. For example, if you want to shift the graph 4 units to the right, 6 units up, and 2 units down, you would first shift it 4 units to the right, then 6 units up, and finally 2 units down.

Q: What is the equation of a function with multiple translations?

A: The equation of a function with multiple translations is found by applying each translation to the original function. For example, if the original function is $f(x) = x^2$ and you want to shift it 4 units to the right, 6 units up, and 2 units down, the equation of the translated function would be $g(x) = (x - 4)^2 + 6 - 2$ .
