Using the form we want to write a that matches the given graph.
We can see that the vertical is the line
Therefore, we have that
Similarly, we see that the horizontal asymptote is the line
With this, we know that
We can write a partial equation of the function.
To find the value of
we can use any of the points on the curve. For simplicity, we will use the point
Therefore, we will substitute
and solve for
Finally, we can write the desired equation.
