Introduction

In mathematics, the intersection of two graphs is a point where the two functions meet. This concept is crucial in various mathematical disciplines, including algebra, geometry, and calculus. In this article, we will explore the intersection of two functions, f(x)=2x+4f(x) = 2x + 4 and g(x)=104xg(x) = 10 - 4^x, and find the solution to the equation 2x+4=104x2x + 4 = 10 - 4^x.

The Functions and Their Graphs

The first function, f(x)=2x+4f(x) = 2x + 4, is a linear function with a slope of 2 and a y-intercept of 4. The graph of this function is a straight line that passes through the point (0, 4) and has a slope of 2.

The second function, g(x)=104xg(x) = 10 - 4^x, is an exponential function with a base of 4 and a vertical shift of 10. The graph of this function is a curve that approaches the x-axis as x approaches negative infinity and has a horizontal asymptote at y = 10.

The Intersection Point

The graphs of f(x)f(x) and g(x)g(x) intersect at the point (1, 6). This means that the two functions have the same value at x = 1, which is 6.

The Equation to Solve

To find the solution to the equation 2x+4=104x2x + 4 = 10 - 4^x, we need to isolate the variable x. We can start by subtracting 4 from both sides of the equation:

2x=64x2x = 6 - 4^x

Using Algebraic Manipulation

We can rewrite the equation as:

2x=64x2x = 6 - 4^x

2x+4x=62x + 4^x = 6

Using Exponential Properties

We can rewrite the equation as:

2x+4x=62x + 4^x = 6

4x=62x4^x = 6 - 2x

Using Logarithmic Properties

We can rewrite the equation as:

4x=62x4^x = 6 - 2x

xlog4=log(62x)x \log 4 = \log (6 - 2x)

Using Properties of Logarithms

We can rewrite the equation as:

xlog4=log(62x)x \log 4 = \log (6 - 2x)

x=log(62x)log4x = \frac{\log (6 - 2x)}{\log 4}

Using Numerical Methods

We can use numerical methods, such as the Newton-Raphson method, to find the solution to the equation.

The Solution

Using numerical methods, we find that the solution to the equation 2x+4=104x2x + 4 = 10 - 4^x is x = 1.

Conclusion

In this article, we explored the intersection of two functions, f(x)=2x+4f(x) = 2x + 4 and g(x)=104xg(x) = 10 - 4^x, and found the solution to the equation 2x+4=104x2x + 4 = 10 - 4^x. We used algebraic manipulation, exponential properties, logarithmic properties, and numerical methods to find the solution. The solution to the equation is x = 1.
