### Re: write a function of this graph :

D alludes to the distance between the horizontal asymptote and the y-value of the graph.
The function, as noted in the answer, is exponential, so the equation is of an exponential form. The

in the equation is simply the result of distribution.
Because D represents the distance between the horizontal asymptote(that is,
) and the y-value of the function, D is equal to 4-y.
