Question 121500: What type of function does the following table of values represent?
x- -21,-18,-15,-12,-9
y- 3,6,12,24,48
Is it arithmetic,quadratic, cubic, or exponential?
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Common differences do not give you a constant difference
so it is not arithmeti, quadratic, or cubic.
I tried fitting it into y = ab^x and got y = 384(2^(x/3)
by solving for a and b.
So it is exponential.
