Rectangle R has varying length l and width w but a constant area f 4ft^2.
A. Express the perimeter P as a function of l. What kind of function is P? What is its domain?
B. Describe the asymptotic behavior of P. What can you say about R because of the behavior?

@ganeshie8 could you help me?

lastdaywork · Answer

Let area = A = l * w

P = 2l + 2w = 2l + 2A/l

anonymous · Answer

ooookkaaayyy...then what?

lastdaywork · Answer

I dont know what to call it -
P = 2l + 2A/l

First term is linear and second is (rectangular) hyperbolic.

lastdaywork · Answer

I think you should try to find its domain yourself..

anonymous · Answer

ya ok. 
could you help with part b?

lastdaywork · Answer

Do you know the definition of asymptote ??

anonymous · Answer

it doesn't meet any distance and it keeps a continuous curve?
