arrow_back Return to Exponential Functions

We want to identify the value of the base of the exponential function from the given graph.

Let's consider the given equation for this graph. Let's first substitute the given point which has as its coordinate into the above formula. This will allow us to find the value of Let's substitute into the above formula.
Solve for
Now we can write our equation. Next, we will substitute other given points, and into the above equation to check it. Let's start from
The second point satisfies the equation. Let's try the last one,
All the given points satisfy the equation. Now we can be sure that
