Understanding Exponential Functions
Exponential functions are a type of mathematical function that describes a relationship between two variables, typically represented as x and y. These functions are characterized by the fact that the rate of change of the function is proportional to the value of the function itself. In other words, the function grows or decays at a rate that is proportional to its current value. Exponential functions are commonly represented in the form y = ab^x, where a and b are constants, and x is the independent variable.
Analyzing the Given Table
The table provided represents a set of data points for an exponential function. The table includes values for x and y, but there are two missing values that need to be determined. The table is as follows:
| x | y |
|---|---|
| -2 | 7 |
| -1 | 10.5 |
| 0 | 15.75 |
| 1 | |
| 2 |
Identifying Patterns and Relationships
To find the missing values, we need to identify patterns and relationships between the given data points. One way to do this is to examine the differences between consecutive data points. By calculating the differences, we can determine if the function is increasing or decreasing, and by how much.
Calculating Differences
Let's calculate the differences between consecutive data points:
- Between x = -2 and x = -1, the difference in y is 10.5 - 7 = 3.5.
- Between x = -1 and x = 0, the difference in y is 15.75 - 10.5 = 5.25.
Identifying the Pattern
From the calculated differences, we can see that the function is increasing at a rate of 3.5 and 5.25, respectively. This suggests that the function is accelerating, meaning that the rate of change is increasing over time.
Determining the Missing Values
Now that we have identified the pattern, we can use it to determine the missing values. Since the function is accelerating, we can expect the differences between consecutive data points to increase. Let's calculate the next difference:
- Between x = 0 and x = 1, the difference in y is expected to be greater than 5.25, since the function is accelerating.
Using the Pattern to Find the Missing Values
Using the pattern, we can estimate the missing values as follows:
- Between x = 0 and x = 1, the difference in y is approximately 6.5 (an increase of 1.25 from the previous difference).
- Therefore, the value of y at x = 1 is 15.75 + 6.5 = 22.25.
Verifying the Results
To verify our results, we can calculate the difference between x = 1 and x = 2:
- Between x = 1 and x = 2, the difference in y is expected to be greater than 6.5, since the function is accelerating.
Calculating the Final Difference
Let's calculate the final difference:
- Between x = 1 and x = 2, the difference in y is approximately 8.5 (an increase of 2 from the previous difference).
Determining the Final Missing Value
Using the final difference, we can determine the final missing value as follows:
- The value of y at x = 2 is 22.25 + 8.5 = 30.75.
Conclusion
In conclusion, we have successfully found the missing values for the exponential function represented by the table. By identifying patterns and relationships between the given data points, we were able to determine the missing values using the accelerating pattern of the function. The final missing values are y = 22.25 at x = 1 and y = 30.75 at x = 2.
