Introduction

Graphing is a powerful tool in mathematics that allows us to visualize and solve equations graphically. In this article, we will explore how to solve the equation e43x=43x+9e^{4-3x}=\frac{4}{3}x+9 by graphing. We will examine the different options for graphing and determine which ones are necessary to solve the equation.

Understanding the Equation

The given equation is e43x=43x+9e^{4-3x}=\frac{4}{3}x+9. This is an exponential equation, where the left-hand side is an exponential function and the right-hand side is a linear function. To solve this equation graphically, we need to find the point of intersection between the two functions.

Graphing the Equation

To graph the equation, we need to graph the two functions separately and then find the point of intersection. The two functions are:

  • Exponential Function: y=e43xy=e^{4-3x}
  • Linear Function: y=43x+9y=\frac{4}{3}x+9

We can graph these functions using a graphing calculator or a computer algebra system.

Graphing Options

Now, let's examine the different options for graphing:

A. y=0y=0

Graphing y=0y=0 is not necessary to solve the equation. This graph represents the x-axis, and it does not intersect with the exponential function.

B. y=43x+9y=\frac{4}{3}x+9

Graphing y=43x+9y=\frac{4}{3}x+9 is necessary to solve the equation. This graph represents the linear function on the right-hand side of the equation.

C. y=e43x43x+9y=e^{4-3x}-\frac{4}{3}x+9

Graphing y=e43x43x+9y=e^{4-3x}-\frac{4}{3}x+9 is not necessary to solve the equation. This graph represents the difference between the exponential function and the linear function, but it does not provide any additional information.

D. y=43x+9+e43xy=\frac{4}{3}x+9+e^{4-3x}

Graphing y=43x+9+e43xy=\frac{4}{3}x+9+e^{4-3x} is not necessary to solve the equation. This graph represents the sum of the linear function and the exponential function, but it does not provide any additional information.

E. y=e43xy=e^{4-3x}

Graphing y=e43xy=e^{4-3x} is necessary to solve the equation. This graph represents the exponential function on the left-hand side of the equation.

Conclusion

In conclusion, to solve the equation e43x=43x+9e^{4-3x}=\frac{4}{3}x+9 by graphing, we need to graph the following equations:

  • Exponential Function: y=e43xy=e^{4-3x}
  • Linear Function: y=43x+9y=\frac{4}{3}x+9

Graphing y=0y=0 is not necessary, and graphing y=e43x43x+9y=e^{4-3x}-\frac{4}{3}x+9, y=43x+9+e43xy=\frac{4}{3}x+9+e^{4-3x}, and y=e43xy=e^{4-3x} does not provide any additional information.

By graphing these two functions, we can find the point of intersection and solve the equation.

Step-by-Step Solution

Here is a step-by-step solution to the equation:

  1. Graph the Exponential Function: Graph the function y=e43xy=e^{4-3x}.
  2. Graph the Linear Function: Graph the function y=43x+9y=\frac{4}{3}x+9.
  3. Find the Point of Intersection: Find the point of intersection between the two functions.
  4. Solve the Equation: The point of intersection represents the solution to the equation.

By following these steps, we can solve the equation e43x=43x+9e^{4-3x}=\frac{4}{3}x+9 by graphing.

Example

Let's consider an example to illustrate the solution.

Suppose we want to solve the equation e43x=43x+9e^{4-3x}=\frac{4}{3}x+9 by graphing. We can graph the two functions using a graphing calculator or a computer algebra system.

Here is a sample graph:
