To check if the given data displays exponential behavior.

Answer to Problem 21PPS
No
Explanation of Solution
Given:
Concept used:
When the domain values ( x values) are at regular intervals [added with same number] and the range values ( y values) have positive common factor [gets multiplied by same number], then the given data displays exponential behavior.
The x values denote the domain values and y values denote the range values.
Observe the row with values of x .
There is an increase of +4 for each value.
Hence, the domain values are at regular intervals.
Similarly, observe the row with values of y.
There is a common factor of -2.
Hence, the range values have common factor.
Here, the domain values are at regular intervals but the range values does not have a positive common factor.
Conclusion:
Therefore, the given data does not display exponential behavior.
