The Table of Values: Unveiling the Constant Ratio of Successive y-values
In mathematics, exponential functions are a fundamental concept that plays a crucial role in various fields, including physics, engineering, and economics. These functions are characterized by their ability to grow or decay at a constant rate, making them essential in modeling real-world phenomena. In this article, we will delve into the world of exponential functions and explore the concept of constant ratio of successive y-values. We will examine a table of values representing an exponential function and determine the constant ratio of successive y-values.
Understanding Exponential Functions
Exponential functions are a type of mathematical function that exhibits exponential growth or decay. They are defined as functions of the form f(x) = ab^x, where a and b are constants, and x is the variable. The constant b is known as the base of the exponential function, and it determines the rate at which the function grows or decays. If the base b is greater than 1, the function grows exponentially, while if the base b is between 0 and 1, the function decays exponentially.

Finding the Constant Ratio of Successive y-values
To find the constant ratio of successive y-values, we need to examine the table of values and calculate the ratio of each successive pair of y-values. We will use the following formula to calculate the ratio:
Ratio = (y2 - y1) / y1
where y1 and y2 are successive y-values.
Calculating the Ratio
Let's calculate the ratio of each successive pair of y-values.
- For x = -2 and x = -1, the ratio is:
Ratio = (10.5 - 7) / 7 = 3.5 / 7 = 0.5
- For x = -1 and x = 0, the ratio is:
Ratio = (15.75 - 10.5) / 10.5 = 5.25 / 10.5 = 0.5
- For x = 0 and x = 1, the ratio is:
Ratio = (23.625 - 15.75) / 15.75 = 7.875 / 15.75 = 0.5
In conclusion, the constant ratio of successive y-values is 0.5. This means that for every successive pair of y-values, the ratio is constant and equal to 0.5. This is a characteristic of exponential functions, where the ratio of successive values is constant and equal to the base of the function.
