For the following exercises, enter the data from each table into a graphing calculator and graph the resulting scatter plots. Determine whether the data from the table could represent a function that is linear, exponential, or logarithmic. $$\begin{array}{|c|c|c|c|c|c|c|c|}\hline x & {1} & {2} & {3} & {4} & {5} & {6} & {7} & {8} & {9} & {10}\\ \hline f(x) & {2.4} & {2.88} & {3.456} & {4.147} & {4.977} & {5.972} & {7.166} & {8.6} & {10.32} & { 12.383}\\ \hline\end{array}$$

Key Concepts

Scatter Plot

A scatter plot is a type of graph that displays values for typically two variables for a set of data. In these plots, each point represents an observation from the data set. Scatter plots are useful for identifying patterns, trends, and potential relationships between the variables, which can help in determining the nature of the relationship (linear, exponential, logarithmic, etc.).

Linear Function

A linear function is one in which the relationship between the independent variable and the dependent variable can be described by a straight line. This means that the change in the dependent variable is constant for each unit change in the independent variable. Linear functions are characterized by a constant rate of change and have the general form f(x) = mx + b, where m is the slope and b is the y-intercept.

Exponential Function

An exponential function is defined by a constant ratio between successive output values, meaning that the function increases or decreases multiplicatively rather than additively. The general form is f(x) = a * b^x, where 'a' is a constant and 'b' is the base of the exponential function. These functions are useful for modeling growth or decay processes where the rate of change is proportional to the value itself.

Logarithmic Function

A logarithmic function is the inverse of an exponential function and is used to model situations where there is a rapid change initially that gradually levels off. It is characterized by a slow rate of growth at higher values and is often represented in the form f(x) = a + b * log(x), where log(x) indicates the logarithm of x. This type of function is useful in contexts where scale invariance or diminishing returns are observed.
