Select the correct statement about the function represented by the table.

B.  It is an exponential function because the y values increases by an equal factor over equal intervals of x value

Step-by-step explanation:

WE are given with a table

Let find the difference in y values  and difference is x values

Difference in x value is 1

LEt check the difference in y values

21- 7 = 16

63- 21= 42

Difference in y values/ x values is not a constant . So it is not linear function

It is an exponential function

Now we consider the y values

7 *3 = 21

21 * 3= 63

63* 3= 189

We can see that y values are increasing by a factor of 3

the y values increases by an equal factor 3 over equal intervals of x value (1)

can you rephrase the question ? it is unclear : -)
