How do I do this and what is the answer? For the function f(x) = x + 5, what is the ordered pair for the point on the graph when x = 4w? A) (4w, x + 5) B) (4w, 4w + 5) C) (x, x + 5) D) (x, 4w + 5)

    Take x + 5, and replace x with 4w. What do you get?

    Exactly. Since f(4w) = 4w + 5, that means the ordered pair has 4w for x and 4w + 5 for y. Which choice has that?

    A is (4w, x + 5) We have 4w for x but 4w + 5 for y, not x + 5 for y.
