$**Solving the Equation $4 e^{2+2 x} = x - 3$ by Graphing**$

Introduction

In this article, we will explore a method to solve the equation $4 e^{2+2 x} = x - 3$ using graphing. This method involves rewriting the equation as a system of equations and then graphing the system to find the solution. We will use a graphing calculator to visualize the graphs and find the point of intersection, which represents the solution to the equation.

Step 1: Write a System of Equations

To solve the equation $4 e^{2+2 x} = x - 3$ , we can rewrite it as a system of equations by setting $y = 4 e^{2+2 x}$ and $y = x - 3$ . This gives us the following system of equations:

$y = 4 e^{2+2 x}$
$y = x - 3$

We can rewrite the first equation as $y = 4 e^{2x+2}$ to make it easier to work with.

Step 2: Graph the System

To graph the system, we can use a graphing calculator to visualize the graphs of the two equations. We will graph each equation separately and then find the point of intersection, which represents the solution to the equation.

Graphing the First Equation

To graph the first equation $y = 4 e^{2x+2}$ , we can use the following steps:

Enter the equation into the graphing calculator: y = 4 * e^(2x+2)
Set the window to a suitable range: x = [-10, 10] and y = [-10, 10]
Graph the equation using the graphing function

The graph of the first equation will be a curve that increases rapidly as x increases.

Graphing the Second Equation

To graph the second equation $y = x - 3$ , we can use the following steps:

Enter the equation into the graphing calculator: y = x - 3
Set the window to a suitable range: x = [-10, 10] and y = [-10, 10]
Graph the equation using the graphing function

The graph of the second equation will be a straight line with a slope of 1 and a y-intercept of -3.

Finding the Point of Intersection

To find the point of intersection, we can use the following steps:

Graph both equations on the same coordinate plane
Use the graphing calculator to find the point of intersection
Read the x and y values of the point of intersection

The point of intersection represents the solution to the equation $4 e^{2+2 x} = x - 3$ .
