A box is formed by cutting squares from the four corners of a 7"-wide by 9"-long sheet of paper and folding up the sides. Suppose the function ff determines the volume of the box (in cubic inches) given a cutout length (in inches). Write a function formula for f. I wrote. f(x) = x(7-2x)(9-2x) It then asks What is the domain of f? and to write it as an interval. I solved for 7-2x>=0 The answer I put was (0,3.5). it marked it correct. But for finding the range of f, I kept getting that one wrong. The answer it said it was is (0, 36.6081). I do not know how they found the range. I thought to evaluate different equations placing 0 as x to find the range. I tried to set it to 0 and solve. When looking up this answer, it says "all real numbers." I'm completely confused.
Can you give me an example of Operations sets?
