Best ResponseYou've already chosen the best response.0so, the inverse of 1/4x=4x

Best ResponseYou've already chosen the best response.0example the inverse of 6x= 1/6x

Best ResponseYou've already chosen the best response.0please answer this for me . what is the inverse of 100x?

anonymous

Best ResponseYou've already chosen the best response.0so then it has to be f^1(x) = 4x  3

Best ResponseYou've already chosen the best response.0nooo. the anser is 1/100x

Best ResponseYou've already chosen the best response.01/20x I'm confused. I hate this

Best ResponseYou've already chosen the best response.0what is the inverse of 15?

anonymous

Best ResponseYou've already chosen the best response.0just from what you've told me I actually think it's f^1(x) = 4x  3 and not the first answer I had. My packet isn't doing a very good job of explaining this.

Best ResponseYou've already chosen the best response.0I guess I thought that the x should be in the parenthesis with the 3 but now I know that was super wrong. So thank you :)

Best ResponseYou've already chosen the best response.0Also I need to find better explanations of this, my packet does a sucky job.

Best ResponseYou've already chosen the best response.0Here are simple steps for inverse: Replace f(x) with y Switch x's and y's, so put x where y is and x where y is. Solve for y Replace y with f^1(x)

Best ResponseYou've already chosen the best response.0So the original expression will be: \(y=\frac{1}{4}x+3\) ok?

Best ResponseYou've already chosen the best response.0Can you guess what switching \(x\) and \(y \) means?

anonymous

Best ResponseYou've already chosen the best response.0okay so switching them I thought meant doing 1/4x= y+3

anonymous

Best ResponseYou've already chosen the best response.0that's where I wasn't sure what I was doing.

Best ResponseYou've already chosen the best response.0No that guess was wrong.. ;)

Best ResponseYou've already chosen the best response.0Switching means simply interchanging... For example: Before switching: \(\color{blue}y=2\color{red}{x}+1\) After switching: \(\color{red}{x}=2\color{blue}y+1\) ok?

Best ResponseYou've already chosen the best response.0yeah okay so the 1/4 would just stay where it was initially.

amilapsn

Best ResponseYou've already chosen the best response.0exactly! So now what the answer would be?

anonymous

Best ResponseYou've already chosen the best response.0it would be f^1(x)= 4x3?

amilapsn

Best ResponseYou've already chosen the best response.0no... Not quite. after switching what would you get?

anonymous

Best ResponseYou've already chosen the best response.0okay so the problem would look like x=1/4y+3 the inverse of addition is subtraction (like said above)

anonymous

Best ResponseYou've already chosen the best response.0iambatman said to solve for y how would I do that?

anonymous

Best ResponseYou've already chosen the best response.0so the first answer I had was right the entire time?

anonymous

Best ResponseYou've already chosen the best response.0@GIL.ojei did we do it wrong the first time around? Would you say that it's right this time?

amilapsn

Best ResponseYou've already chosen the best response.0yep.. BTW solving for y means expressing y in terms of x. that means you've got \(x=\frac{1}{4}y+3\) after switching.. After solving for \(y \) means just getting \(y=4(x3)\)

Best ResponseYou've already chosen the best response.0@lily1021 IS Y=4X12 OR 4(X3) IN YOUR OPTION?

anonymous

Best ResponseYou've already chosen the best response.0yep those were both in my options which why I was torn between them. I didn't know what made them different.

anonymous

Best ResponseYou've already chosen the best response.0oh wait I missed the 12 in your post. No y=4x12 is not in my options but 4(x3) is

anonymous

Best ResponseYou've already chosen the best response.0okay thank you. and big thanks to @amilapsn for coming back and helping me through this. It means so much to me you have no idea lol :)

Best ResponseYou've already chosen the best response.0I have another similar one I have to solve but I think it would kinda be the same. Can I post so you can check? I'll do it in a new post so I can medal you.
