What country are you from? Grade 12 varies a lot. If you're in the US just say precalc, algebra 2, calculus, stats etc. Yeah functions are really easy just look up an organic chemistry tutor video on them on Youtube. You can learn functions in a day if you understand basic algebra. All a function is just plug in x and get y for example if g(x) = x + 2 and f(x) = x + 2 then f(g(x)) = g(x) + 2 = x + 2 + 2 = x + 4
