I recommend using the Desmos graphing calculator (you can find it pretty easily by just googling it). You can enter any function and it will graph it for you.
im a bit confused. do we solve it in that order, for A first then C then B? because im sure if you solve it in a different order youll get a different result
@@skzafir721no you can literally do any of them in any order. After some time you'll eventually be able to do it all simultaneously without the need to plot them.
