Question

Which set of ordered pairs could be generated by an exponential function ?

Answer 1

C

Explanation:

Answer 2

The third choice is the correct answer

Explanation:

The set of ordered pairs which could be generated by an exponential function is

`(1,(1)/(2)),(2,(1)/(4)),(3,(1)/(8)),(4,(1)/(16))`

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of

`r=(1)/(4)/ (1)/(2)`

`r=(1)/(4)* 2`

`r=(1)/(2)`

This makes it exponential.
