Introduction

In mathematics, functions are used to describe relationships between variables. Transforming functions is an essential concept in mathematics, as it allows us to create new functions from existing ones. In this article, we will explore the steps required to transform the function f(x)=6xf(x)=6^x into g(x)=6x−5−7g(x)=6^{x-5}-7. We will examine the different types of transformations and provide a step-by-step guide on how to perform them.

Understanding Function Transformations

Function transformations involve changing the position, shape, or size of a function. There are four main types of transformations:

  • Horizontal Shift: This type of transformation involves moving the function to the left or right.
  • Vertical Shift: This type of transformation involves moving the function up or down.
  • Horizontal Stretch or Compression: This type of transformation involves changing the width of the function.
  • Vertical Stretch or Compression: This type of transformation involves changing the height of the function.

Transforming f(x)=6xf(x)=6^x into g(x)=6x−5−7g(x)=6^{x-5}-7

To transform f(x)=6xf(x)=6^x into g(x)=6x−5−7g(x)=6^{x-5}-7, we need to perform two types of transformations:

  1. Horizontal Shift: We need to shift the function f(x)=6xf(x)=6^x five units to the right.
  2. Vertical Shift: We need to shift the function f(x)=6xf(x)=6^x seven units down.

Step-by-Step Guide

Step 1: Horizontal Shift

To shift the function f(x)=6xf(x)=6^x five units to the right, we need to replace xx with x−5x-5. This will give us the new function f(x−5)=6x−5f(x-5)=6^{x-5}.

f(x) = 6^x
f(x-5) = 6^(x-5)

Step 2: Vertical Shift

To shift the function f(x−5)=6x−5f(x-5)=6^{x-5} seven units down, we need to subtract 7 from the function. This will give us the new function g(x)=6x−5−7g(x)=6^{x-5}-7.

f(x-5) = 6^(x-5)
g(x) = 6^(x-5) - 7

Conclusion

In conclusion, to transform the function f(x)=6xf(x)=6^x into g(x)=6x−5−7g(x)=6^{x-5}-7, we need to perform two types of transformations: a horizontal shift of five units to the right and a vertical shift of seven units down. By following the step-by-step guide provided in this article, you can easily transform functions and create new ones.

Common Mistakes to Avoid

When transforming functions, it's essential to avoid common mistakes. Here are a few:

  • Incorrect Horizontal Shift: Make sure to replace xx with x−hx-h when shifting the function horizontally.
  • Incorrect Vertical Shift: Make sure to add or subtract the correct value when shifting the function vertically.
  • Incorrect Order of Transformations: Make sure to perform the transformations in the correct order. For example, if you need to shift the function horizontally and then vertically, make sure to perform the horizontal shift first.

Real-World Applications

Function transformations have numerous real-world applications. Here are a few:

  • Modeling Population Growth: Function transformations can be used to model population growth and understand how different factors affect population size.
  • Analyzing Economic Data: Function transformations can be used to analyze economic data and understand how different factors affect economic growth.
  • Designing Electrical Circuits: Function transformations can be used to design electrical circuits and understand how different components interact.

Q&A

Q: What is a horizontal shift in function transformations?

A: A horizontal shift in function transformations involves moving the function to the left or right. To shift a function horizontally, you need to replace xx with x−hx-h, where hh is the number of units you want to shift the function.

Q: What is a vertical shift in function transformations?

A: A vertical shift in function transformations involves moving the function up or down. To shift a function vertically, you need to add or subtract a value from the function.

Q: How do I determine the type of transformation needed?

A: To determine the type of transformation needed, you need to analyze the given function and the target function. Look for any changes in the input variable, the output variable, or the function itself.

Q: What is the difference between a horizontal stretch and a horizontal compression?

A: A horizontal stretch involves increasing the width of the function, while a horizontal compression involves decreasing the width of the function.

Q: What is the difference between a vertical stretch and a vertical compression?

A: A vertical stretch involves increasing the height of the function, while a vertical compression involves decreasing the height of the function.

Q: Can I combine multiple transformations?

A: Yes, you can combine multiple transformations to achieve the desired result. However, make sure to perform the transformations in the correct order.

Q: How do I know which transformation to perform first?

A: To determine which transformation to perform first, analyze the given function and the target function. Look for any changes in the input variable, the output variable, or the function itself.
