Best ResponseYou've already chosen the best response.1try solving y = 3x + 3 for x. Tell me what you get or draw it out

Best ResponseYou've already chosen the best response.1f(x) minus 3 is NOT the same as f(3)

Best ResponseYou've already chosen the best response.1you simply leave it as f(x)  3

Best ResponseYou've already chosen the best response.1now swap x and f(x), then replace f(x) with the inverse function notation

Best ResponseYou've already chosen the best response.0Wouldn't it be easier to swap the variables first and then solve for y ? @jim_thompson5910

Best ResponseYou've already chosen the best response.1yes that is a possibility. Either way you get to the same answer

Best ResponseYou've already chosen the best response.1swap x and f(x) then use the inverse notation in place of f(x) dw:1436929571273:dw

Best ResponseYou've already chosen the best response.0yeah we are looking for the inverse We just swap the variables x and y and then solve for y ... same process. only swapping first in my opinion is better.
