Question 924640: Please help me solve:
The volume of a rectangular box is given by the function V(w)= (60-4w)w^2. What is a reasonable domain for the function in this situation? Express the domain as an inequality, in interval notation, and in set notation.
Answer by josgarithmetic(39616)   (Show Source):
You can put this solution on YOUR website! The volume must be a positive value. Does that tell you something? w would be one of the dimensions, so w must also be a positive value, but that is not enough. Back to the resulting volume: It must be a positive value, so what does that tell you?
