    The x values begin at 0 and move up by 1. The y values begin at 2 and drop down by 1. So, I tried an expression that would give 2 when x is 0. f(x) = 2 - x That works if x = 0 because f(0) = 2 - 0 = 2

    Keeping the same function f(x) = 2 - x, I put 1 in for x and got f(1) = 2 - 1 = 1. Trying the other x values in the same way, I decided that the rule could be f(x) = 2 - x See what you think. @Darkhornet10
