how do i graph this equation :-

Question

The universal company found that monthly demand for its new lap tops. t months after placing the lap tops on the market was given by:

D(t)= 2000-1500e^-0.05t
t=o
Graph this function and answer the following questions
a.what is the demand after 1 month?(initially)

( y = A-B.C^-kt ) <--Hint

Answer 1

D(t)=2000-1500e^-0.05t is shown above. When t=0 (initial condition) D(0)=2000-1500=500 as shown by the y-intercept. After a month it rises to about 573. After many months the demand starts to approach 2000 because the exponential term gets smaller. So demand cannot exceed 2000.
