Answer:
[tex]7^{x}[/tex] or "7 to the power of x"
Step-by-step 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 [tex]2^{x}[/tex]
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 ([tex]7^{x}[/tex]) to get the rest of our table.
[tex]7^{0}[/tex] = 1
[tex]7^{1}[/tex] = 7
[tex]7^{2}[/tex] = 49
[tex]7^{3}[/tex] = 343
Now, we know our exponential function is [tex]7^{x}[/tex]
Hope this Helps! :)
