why might function notation be important? the reasons notation is used?
Once you get out of three dimensional functions, it is hard to write it any other way. Example:
f(x,y,z,t, u, v)=2x +y*e^{t} + uv 3zuv^{2}

to rent a dvd a customer must pay $3.99 plus $0.99 for every day that it is late, write a rule in function notation for this situation?
f(x)=3.99+0.99x
