By using the information given on the graph, we can see that a = 3.
<h3>
How to find the value of a?</h3>
Here we have an exponential of the form:

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

From the first equation we get that p = 4, replacing that on the second one we get:

So we conclude that a = 3.
