Function { G $}$ Can Be Thought Of As A Translated (shifted) Version Of { F(x) = X^2 $}$.Write The Equation For { G(x) $}$.
Introduction
In mathematics, functions are essential building blocks for modeling real-world phenomena. A function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range). When we translate a function, we shift its graph horizontally or vertically, resulting in a new function. In this article, we will explore the concept of function translation and write the equation for a translated version of the function f(x) = x^2.
What is Function Translation?
Function translation is a process of shifting the graph of a function horizontally or vertically. This can be achieved by adding or subtracting a constant value from the input variable x or the output variable f(x). The resulting function is called a translated or shifted version of the original function.
Types of Function Translation
There are two types of function translations:
- Horizontal Translation: This involves shifting the graph of a function horizontally to the left or right. This can be achieved by adding or subtracting a constant value from the input variable x.
- Vertical Translation: This involves shifting the graph of a function vertically up or down. This can be achieved by adding or subtracting a constant value from the output variable f(x).
Writing the Equation for a Translated Function
To write the equation for a translated function, we need to understand how the translation affects the original function. Let's consider the function f(x) = x^2 as an example.
Suppose we want to translate the function f(x) = x^2 by 3 units to the right and 2 units up. To do this, we need to add 3 to the input variable x and add 2 to the output variable f(x).
The equation for the translated function g(x) can be written as:
g(x) = (x - 3)^2 + 2
This equation represents a translated version of the function f(x) = x^2, shifted 3 units to the right and 2 units up.
Example 1: Translating f(x) = x^2 by 2 Units to the Left
Suppose we want to translate the function f(x) = x^2 by 2 units to the left. To do this, we need to subtract 2 from the input variable x.
The equation for the translated function g(x) can be written as:
g(x) = (x + 2)^2
This equation represents a translated version of the function f(x) = x^2, shifted 2 units to the left.
Example 2: Translating f(x) = x^2 by 4 Units Up
Suppose we want to translate the function f(x) = x^2 by 4 units up. To do this, we need to add 4 to the output variable f(x).
The equation for the translated function g(x) can be written as:
g(x) = (x)^2 + 4
This equation represents a translated version of the function f(x) = x^2, shifted 4 units up.

We also provided examples of translating the function f(x) = x^2 by different amounts to the left or right and up or down.

Q: How do I translate a function horizontally?
A: To translate a function horizontally, you need to add or subtract a constant value from the input variable x. For example, if you want to translate the function f(x) = x^2 by 3 units to the right, you would write the equation as g(x) = (x - 3)^2.

Q: Can I translate a function by both horizontally and vertically?
A: Yes, you can translate a function by both horizontally and vertically. For example, if you want to translate the function f(x) = x^2 by 3 units to the right and 2 units up, you would write the equation as g(x) = (x - 3)^2 + 2.
Q: How do I determine the equation for a translated function?
A: To determine the equation for a translated function, you need to understand how the translation affects the original function. You can do this by adding or subtracting a constant value from the input variable x or the output variable f(x).
Q: What are some common mistakes to avoid when translating functions?
A: Some common mistakes to avoid when translating functions include:
- Not understanding the direction of the translation (e.g., left vs. right)
- Not using the correct notation for the translated function (e.g., g(x) vs. f(x))
- Not checking the domain and range of the translated function
