Introduction

In mathematics, an inverse equation is a type of equation that represents the inverse operation of another equation. In other words, it is an equation that "reverses" the original equation. Inverse equations are commonly used in algebra, calculus, and other branches of mathematics to solve problems and model real-world situations. In this article, we will explore the concept of inverse equations and learn how to find the inverse of a given equation.

What is an Inverse Equation?

An inverse equation is an equation that represents the inverse operation of another equation. For example, if we have an equation of the form $y = f(x)$ , then the inverse equation is of the form $x = f^{-1}(y)$ . In other words, the inverse equation "reverses" the original equation by swapping the variables $x$ and $y$ .

How to Find the Inverse of a Given Equation

To find the inverse of a given equation, we need to follow these steps:

Swap the variables: Swap the variables $x$ and $y$ in the original equation.
Solve for y: Solve the resulting equation for $y$ .
Simplify: Simplify the resulting equation to obtain the inverse equation.

Step 1: Swap the Variables

Let's start by swapping the variables $x$ and $y$ in the original equation. The original equation is $(x-4)^2-\frac{2}{3}=6y-12$ . Swapping the variables, we get:

y-4)^2-\frac{2}{3}=6x-12

Step 2: Solve for y

Now, let's solve the resulting equation for $y$ . We can start by adding $\frac{2}{3}$ to both sides of the equation:

(y-4)^2=6x-12+\frac{2}{3}

Next, we can take the square root of both sides of the equation:

y-4=\pm\sqrt{6x-12+\frac{2}{3}}

Step 3: Simplify

Finally, let's simplify the resulting equation to obtain the inverse equation. We can start by adding $4$ to both sides of the equation:

y=\pm4+\sqrt{6x-12+\frac{2}{3}}

Simplifying further, we get:

y=\pm4+\sqrt{6x-\frac{34}{3}}

Which Equation is the Inverse of the Given Equation?

Now that we have found the inverse equation, let's compare it with the given options. We have:

A. $y=\frac{1}{6}x^2-\frac{4}{3}x+\frac{43}{9}$

B. $y=4\pm\sqrt{6x-\frac{34}{3}}$

C. $y=-4\pm\sqrt{6x-\frac{34}{3}}$

D. (Not given)

Comparing the inverse equation we found with the given options, we can see that option B is the correct answer.

Conclusion

In this article, we learned about inverse equations and how to find the inverse of a given equation. We also compared the inverse equation we found with the given options and determined that option B is the correct answer. Inverse equations are an important concept in mathematics, and understanding how to find the inverse of a given equation is crucial for solving problems and modeling real-world situations.
