Answer:


image or "7 to the power of x"

Explanation:

Ok! So an exponential function is a function with a variable as an exponent.

x y

0 1

1 7

2 49

3 343

An example exponential function is
image

Now! Let's look at what number multiplies by each of our "y" values to get the following "y" value. 7!

Now let's see if we can put 7 to the power of x (
image) to get the rest of our table.


image = 1


image = 7


image = 49


image = 343

Now, we know our exponential function is
image

Hope this Helps! :)
