Question

If \(f(x)=\Large\frac{ 2x-1 }{ x^2 }\) what is the value of \(f(-0.1)\) ?

Answer 1

I think I have to do inverse..

Answer 2

just substitute all x variables with -0.1

Inverse? are you looking for \(\sf f^{-1}(-0.1)\) and not \(\sf f(-0.1)\)?

Answer 3

I'm really not sure, but I think it's just substitute..

Answer 4

maybe take a screenshot of your question :)

If it says \(\sf f^{-1}(-0.1)\) then you are looking for inverse, but if it only says \(\sf f(-0.1)\) then you just have to substitute x= -0.1

Answer 5

Yes. The second one.

Answer 6

oh alright, then you just have to substitute x.

Do you still need help with that?

Answer 7

I'm solving it right now..

Answer 8

okay :)

let's see if we got the same

Answer 9

I got -120.
