Answer:
Option (A)
Step-by-step explanation:
x y Ratio [tex](\frac{y_2}{y_1})[/tex]
1 7 -
2 21 [tex]\frac{21}{7}=3[/tex]
3 63 [tex]\frac{63}{21}=3[/tex]
4 189 [tex]\frac{189}{63}=3[/tex]
5 567 [tex]\frac{567}{189}=3[/tex]
Since, there is a common ratio in each successive term of y over the equal interval of x values,
Given table will represent an exponential function.
Therefore, Option (A) will be the correct option.
