Hey guys so I'm currently working on a problem:
I was able to attain the function P(L) which is:A rectangle has area 16 m2. Express the perimeter of the rectangle as a function of the length L of one of its sides.
My issue comes with the next question which is:
I think it's the wording that has me confused. I'm assuming the answer is -infinity to +infinity with the exclusion of 0. However, I made the assumption that because a rectangle cannot have negative sides I also excluded values less than 0 and input (0,+infinity) as the answer and got it wrong.State the domain of P. (Assume the length of the rectangle is larger than its width. Enter your answer using interval notation.)
Just wondering if I'm interpreting the question wrong cause I can't seem to get it right.
