What is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)

Note: The complete question, along with the graph, is attached below.

The value of a = 3

Step-by-step explanation:

Given the function

From the attached graph, it is clear that

at x = 0,

        ∵

Thus

When x = 0, the y-intercept will be:

From the attached figure, it is clear that

at x = 0, the value of y = 3

so

putting y = 3 in the equation

3 = a            ∵

Therefore, the value of a = 3

true
