1. The problem statement, all variables and given/known data If the maximum allowable width, w, of the wall is 100 cm, what are the domain and rand of the function? Remember to include units for both the domain and range. 2. Relevant equations w(d)=2d w(d)=100, so 100=2d, there fore d=100/2 3. The attempt at a solution Domain: d (less than or equal to) 50cm Range: all real numbers Sorry, I'm a bit rusty on finding D and R. Thanks for the help, here is the original question via PDF, I got part (a). I am just unsure about my D and R ( I am a perfectionist) ALSO: For part (a) I got : A(d)=((Pi)(d^2))/2, correct? THANK YOU VERY MUCH.
