Question

f(x)=x+3 /x
inverse

Answer 1

Do you mean what you have written, \(x + \dfrac{3}{x}\), or did you mean \(\dfrac{x+3}{x}\)?

Answer 2

oh sorry, yeah the second one

Answer 3

See if you can fix what you have written so that your intent is represented. It's important to be able to communicate.

Answer 4

don't really know how to work it but i think i fixed it better

Answer 5

For \(y = \dfrac{x+3}{x}\), the standard procedure is to swap and solve. Technically, the "solve" is not necessary, but most folks like it that way.

\(x = \dfrac{y+3}{y}\)

That's it!!

Okay, now solve for y.

P.S. Use parentheses to clarify intent.

Answer 6

Ahhh, okay. Thank you for your help + tip :)
