We conclude that the exponential function is:
f(x) = -1*(2)ˣ
<h3>
How to find the exponential function?</h3>
Here we know that we have an exponential function of the form:

And we know two points on the function, that are:

Then we have a system of equations to solve, which is:

From the first equation we can solve:

Replacing that in the other equation we can get:

Now that we know the value of a, we can get the value of b:

In this way, we conclude that the exponential function is:
