The values in the table represent an exponential function. what is the common ratio of the associated geometric sequence
x y
1 8
2 32
3 128
4 512
5 2048
a.4 b.24 c.40 d.8

  A.  4

Step-by-step explanation:

Pick two terms with consecutive x-values and find their ratio. That is the common ratio.

 for x = 2 and x = 1,

 r = 32/8 = 4

The common ratio is 4.

You can check other pairs of terms if you want to confirm.

  r = 2048/512 = 4 . . . . for x=5 and 4.

the first one, all those points on the line just make a strait line.
