In math so far I have learned how graphing functions. When you are graphing functions you first make a chart, x is the impute and y is the output. You start with an equation like 3+x=y and then you plug in different numbers for x like -2, -1, 0, 1, and 2. Then you use the x’s for the x access and the y for the y access, then you’ve graphed a function.
