Introduction

In mathematics, an exponential function is a type of function that exhibits exponential growth or decay. It is characterized by a constant rate of change, which is a key feature that distinguishes it from other types of functions. In this article, we will explore an exponential function represented by a table and determine the multiplicative rate of the function.

Understanding Exponential Functions

An exponential function is a function of the form y=abxy = ab^x, where aa and bb are constants, and xx is the variable. The constant bb is called the base of the exponential function, and it determines the rate of growth or decay of the function. If b>1b > 1, the function exhibits exponential growth, and if 0<b<10 < b < 1, the function exhibits exponential decay.

Analyzing the Table

The table represents an exponential function with the following values:

xx yy
1 6
2 4
3 83\frac{8}{3}
4 169\frac{16}{9}

To determine the multiplicative rate of the function, we need to examine the relationship between the values of xx and yy. Let's start by looking at the ratio of consecutive values of yy.

Calculating the Ratio of Consecutive Values of yy

The ratio of consecutive values of yy is given by:

yn+1yn=834=23\frac{y_{n+1}}{y_n} = \frac{\frac{8}{3}}{4} = \frac{2}{3}

This ratio is constant, which indicates that the function is exponential. The constant ratio of 23\frac{2}{3} is the multiplicative rate of the function.

Determining the Base of the Exponential Function

The base of the exponential function is the constant ratio that we calculated earlier. In this case, the base is 23\frac{2}{3}. To confirm this, we can rewrite the function in the form y=abxy = ab^x.

Rewriting the Function in the Form y=abxy = ab^x

Let's rewrite the function using the values of xx and yy from the table:

y=6(23)x1y = 6 \left(\frac{2}{3}\right)^{x-1}

This is the exponential function represented by the table. The base of the function is 23\frac{2}{3}, which is the multiplicative rate of the function.

Conclusion

In this article, we analyzed an exponential function represented by a table and determined the multiplicative rate of the function. We calculated the ratio of consecutive values of yy and found that it is constant, which indicates that the function is exponential. We then rewrote the function in the form y=abxy = ab^x and confirmed that the base of the function is the multiplicative rate. The multiplicative rate of the function is 23\frac{2}{3}.

Applications of Exponential Functions

Exponential functions have numerous applications in mathematics, science, and engineering. Some examples include:

  • Population growth: Exponential functions can be used to model population growth, where the population grows at a constant rate.
  • Financial modeling: Exponential functions can be used to model financial growth, where the value of an investment grows at a constant rate.
  • Physics: Exponential functions can be used to model the decay of radioactive substances, where the decay rate is constant.
