Noticing the regularity in the way terms cancel when expanding ( x - 1 x 1 ( x - 1 x 2 x 1 and ( x - 1 x 3 x 2 x 1) might lead them to the general formula for the sum. I already found this information, so I can plug that into the equation and solve. When we plug, say, 5, into the f function, we'd get 26 out. 2 always gives you 3, 5 always gives you 6, and 7 always gives you. Remember that it is okay to have multiple buttons that give you the same thing, like you see here with 2, 3, 4 and 5 all giving you. I first want to label what I am supposed to solve for. What operation would we need to do that? Okay, so instead of calling the outputs y, the outputs from the f function will be called f( x and the outputs from the g function will be called g( x ). You push the. Mathematically proficient students try to communicate precisely to others. Mathematically proficient students make sense of quantities and their relationships in problem situations.
