The graph is an illustration of an exponential function

The equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]

How to determine the equation of the graph

From the graph, we have the following ordered pairs

(x,y) = (0, 25.5), (1, 15.3) and (2, 9.18)

An exponential function is represented as:

[tex]y = ab^x[/tex]

When x = 0, we have:

[tex]25.5 = ab^0[/tex]

[tex]a = 25.5[/tex]

When x = 1, we have:

[tex]15.3 = ab^1[/tex]

[tex]15.3 = ab[/tex]

Substitute 25.5 for a

[tex]15.3 = 25.5b\\[/tex]

Solve for b

[tex]b = 0.6[/tex]

So, the exponential equation is:

[tex]y = 25.5 * 0.6^x[/tex]

Hence, the exponential equation of the graph is: [tex]y = 25.5 * 0.6^x[/tex]
