For this case we have a function of the form:
Where,
A: initial amount
b: decrease rate
x: time in days
Substituting values we have:
Therefore, the graph of the function is a decreasing exponential function in the first quadrant and that has an initial value of 40.
Answer:
graph of exponential function going from left to right in quadrant 1 through the point 0, 40 and approaching the x axis
