Best ResponseYou've already chosen the best response.1we graph the original f(x) first and then apply these transformations...

Best ResponseYou've already chosen the best response.3Just by rule.... f(x)+k = vertical shift kf(x) = vertical stretch/shrink (depending) f(x+k) = phase shift, also known as a horizantal shift. f(kx) = Horizantal stretch/shrink Those are the rules to always use.

Best ResponseYou've already chosen the best response.3I don't know how else to explain just by rule....forgive me @UsukiDoll if you or anyone thought this was my way of giving out an answer. Just thought I would give them a key to help them identify what they are handling with other problems.
