Answer: Table 3
Explanation:
exponential relationship means the y value is increasing/decreasing exponentially
In table 1: the value of y is NOT increasing/decreasing exponentially as 2 is being added continuously (linear), so not table 1
In table 2: the value of y is NOT increasing/decreasing exponentially as 4 is being subtracted continuously (linear), so not table 2
In table 3: the value of y IS increasing exponentially as the y variable is multiplied by 2, so table 3
In table 4: the value of y is NOT increasing exponentially as the y variable is only being increased by 5 constantly (linear), so not 4
