Question

HELPPP how do i write an exponential function?!

the table is
x: 0 1 2 3
y: 1 7 49 343

Answer 1

`7^(x)` 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
`2^(x)`

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 (
`7^(x)`) to get the rest of our table.

`7^(0)` = 1

`7^(1)` = 7

`7^(2)` = 49

`7^(3)` = 343

Now, we know our exponential function is
`7^(x)`

Hope this Helps! :)
