Question

is this table an exponential function?
x = 1, 2, 3, 4
y = -1, -8, -27, -64

Answer 1

yes

Answer 2

yes is the answer

Answer 3

Actually it is not. An exponential function will have y values that look something like this:

1, 4, 16, 64

Answer 4

Notice this:

1 * 4 = 4
4 * 4 = 16
16 * 4 = 64

Answer 5

Now when we compare that with the given y value here:

-1 * 8 = -8
-8 * 8 = -64

As you can see, -8 * 8 does NOT = -27.

Answer 6

So the values are not consistent making it not exponential.

Answer 7

oh okay, i get it thank you very much !!!
