Helping my daughter with ratio table homework. I do not understand the concept of the tables. Here is one of her questions that
she has to answer in a table. A book store bought 160 copies of a book from the publisher for $4000. If the store gives away 2 books, how much money will it lose?
F(x) = 3(x-4)^2-38 because finding the perfect square would get you f(x)+38=3(x^2-8x+16) and then finding the squareroot of that and moving the constant on the left back to the right would leave u with f(x)=3(x-4)^2-38
