Here are graphs of the area covered by two different types of mold d days after they were first measured.  1. What are the approximate coordinates of the point of intersection of the two graphs? What does this mean in terms of the two mold populations?  2. The area of mold A is given by the function A ( d ) = 100 ⋅ e 0.25 d. When will this mold cover 1000 square millimeters? Explain your reasoning.
