Does the table represent a exponential function?

x 1 2 3 4
y-1 -8 -27 -64

A.) Yes
B.) No

I think it's yes but not sure.
Thank you.

sorry. no. it's a power function, not an exponential.

So is the answer NO? Thank You.

Whats The Answer ?

no.

To determine if the table represents an exponential function, we need to check if the ratio between consecutive y-values is constant.

In this case, let's calculate the ratios for each pair of consecutive y-values:

-1 / (-8) = 1/8
-8 / (-27) = 8/27
-27 / (-64) = 27/64

If the ratios are constant, then the table represents an exponential function.

So, in this case, let's compare the ratios we calculated:
1/8 ≠ 8/27 ≠ 27/64

Since the ratios are not constant, the table does not represent an exponential function.

Therefore, the answer is B.) No.

Please note that this conclusion is based on the given data in the table.

yes. y = -x^3
