medal A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x − 1) where x is the number of hours. What is the function that shows total sales, including the first hour?

    answer choices s(x) = 15 (x-1) -120 s(x)= 120x-15 s(x) = 120 +15 (x-1) s(x) = 120-15(x-1)

    So the function starts with : s(x) = 120 + ( I put a + after 120 because we know that there are following sales after the first hour ). Then, the sales are s(x) = 15 (x-1). So this is the second part of your function. So what's the answer?

    If you look at the graph and graph (-1, 0), (-3, 1), or (-5, 2) which one ends up on f(x)?

    answer choices are Yes , at a point with a postive x-coordinate Yes , at a point with a negative x-coordinate Yes, at a point where x is zero No , they will not intersect

    That's right, so now we know that it does intersect, but where does it intersect? At zero? At a point with a negative x-coordinate? At a point with a positive x-coordinate?

    The answer is 8/17, but I am not very familiar with cosines so if you want to understand why that is the answer click the link: http://openstudy.com/study#/updates/53c05ddce4b05c273e9be461
