Best ResponseYou've already chosen the best response.2they are basically asking you to solve \(3(x+2)  4=2\)

Best ResponseYou've already chosen the best response.2when you `solve for the inverse function`, you swap x and y, then solve for y so when you plug x = 2 into the inverse, you are really plugging in y = 2 into the original

Best ResponseYou've already chosen the best response.2did you solve \(3(x+2)  4 = 2\) for x?

Best ResponseYou've already chosen the best response.2Let's check your answer 3(x+2)  4 = 2 3(8+2)  4 = 2 ... replace x with 8 3(10)  4 = 2 30  4 = 2 26 = 2 ... this equation is false, so x = 8 is not the solution

Best ResponseYou've already chosen the best response.2scroll back up. I explain how you actually replace y with 2

Best ResponseYou've already chosen the best response.2f(x) = 3(x+2)  4 is the same as y = 3(x+2)  4

Best ResponseYou've already chosen the best response.2yep x = 0 makes 2 = 3(x+2)  4 true
