Understanding Exponential Functions and Transformations
Exponential functions are a fundamental concept in mathematics, and understanding how to transform them is crucial for solving various mathematical problems. In this article, we will delve into the world of exponential functions and explore how to transform them using horizontal compression.
What are Exponential Functions?
Exponential functions are a type of mathematical function that describes a relationship between two variables, typically denoted as x and y. The general form of an exponential function is:
f(x) = ab^x
where a and b are constants, and x is the variable. The base b is the key component of an exponential function, and it determines the rate at which the function grows or decays.
Understanding Horizontal Compression
Horizontal compression is a type of transformation that involves compressing a function horizontally by a certain factor. This means that the function is stretched or compressed in the x-direction, resulting in a change in the function's shape and position.
Transforming Exponential Functions using Horizontal Compression
When transforming an exponential function using horizontal compression, we need to consider the factor by which the function is compressed. In this case, the function f(x) = 7^x + 1 is transformed to function g through a horizontal compression by a factor of 1/3.
To perform a horizontal compression, we need to multiply the input variable x by the compression factor. In this case, the compression factor is 1/3, so we multiply x by 1/3 to get the new input variable.
Deriving the Equation for the Transformed Function
To derive the equation for the transformed function g, we need to substitute the new input variable into the original function f(x) = 7^x + 1.
Let's denote the new input variable as x'. We can express x' in terms of x as follows:
x' = (1/3)x
Now, we can substitute x' into the original function f(x) = 7^x + 1 to get the equation for the transformed function g:
g(x') = 7^(x'/1) + 1
Simplifying the equation, we get:
g(x') = 7^(3x) + 1
Simplifying the Equation
To simplify the equation further, we can rewrite it in terms of x instead of x'. We can do this by substituting x' = (1/3)x into the equation:
g(x) = 7^(3x) + 1
This is the equation for the transformed function g.
Conclusion
In this article, we explored how to transform exponential functions using horizontal compression. We derived the equation for the transformed function g by substituting the new input variable into the original function f(x) = 7^x + 1. The resulting equation is g(x) = 7^(3x) + 1.
Final Answer
The final answer is g(x) = 7^(3x) + 1.
