A textbook company will ship a box of textbooks to college students. The weight of the box in pounds can be determined by the function w(x)=7.5x+2w\left(x\right)=7.5x+2  , where x is the number of textbooks in the box. The company requires a student to order at least 2 books but not more than 6 boks. What is the range of the funciton for this situation?

2≤x≤162\le x\le16  

17≤y≤4717\le y\le47  

{17, 24.5, 32, 39.5, 47}\left\{17,\ 24.5,\ 32,\ 39.5,\ 47\right\}  

{2, 3, 4, 5, 6}\left\{2,\ 3,\ 4,\ 5,\ 6\right\}

Angelica writes a function f with a domain of all real numbers and a range of {−13}\left\{-13\right\}  . Which of the following could be the function she wrote?

f(x)=x−13f\left(x\right)=x-13  

f(x)=13xf\left(x\right)=13x  

f(x)=−13f\left(x\right)=-13  

f(x)=x+13f\left(x\right)=x+13
