I especially need the answer to part 4. Thanks!

The rate at which a cell absorbs an external signalling molecule x through the cell membrane can be described by the absorption function
A(x)
1. Calculate A'(x) and find a value for x such that the absorption function has a horizontal tangent line.
2. What is the absorption rate at this value of x ?
3. Find this tangent line.
4. Would you expect this absorption function to be the same for all cell types and for all signalling molecules x?
