Answer:
Table 3 represents an exponential function.
Explanation:
Exponential function is in a form of
![y=ab^x](https://img.qammunity.org/2019/formulas/mathematics/college/h6f3tn5p9rzzksznrvdqdhrw613dtzqydg.png)
We have to check each table and find the function of each table
Table 1:
x : 1 2 3 4 5
y : 5 10 15 20 25
y=5x
It is linear function which satisfy the table value.
This is false.
Table 2:
x : 1 2 3 4 5
y : 5 20 45 80 125
![y=5x^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/yg4dhrvtvf0s5qat68787j1yp5darni72b.png)
It is a quadratic equation which satisfy the table value.
This is false.
Table 3:
x : 1 2 3 4 5
y : 5 25 125 625 3125
![y=5^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/ym5ynpklvzxns94v8zv4ubcziq7eg7rnbb.png)
This is an exponential function which satisfy the table value.
This is true.
Table 4:
x : 1 2 3 4 5
y : 6 11 16 21 26
![y=5x+1](https://img.qammunity.org/2019/formulas/mathematics/high-school/cx8wvsnyoixl9ch20ixb61f8lrlzmtfnn9.png)
This is a linear equation which satisfy the table value.
This is false.
Thus, Table 3 represents an exponential function.
