Question

F -1(x) if F(x) = x + 3

Answer 1

F-1(x)= x-3

Answer 2

You mean : \(f^{-1}(x)\)

Right??

Answer 3

Let F(x) = y

So:

y = x + 3

Find x here:


x = y - 3

Now here just flip or exchange x and y:

y = x - 3

But now here : y = Inverse of F(x)..

So:

\(F^{-1}(x) = x - 3\).

Answer 4

but it said +3

Answer 5

That is \(F(x) = x + 3\)

But \(F^{-1}(x) = x - 3\)

Answer 6

Ok ill try again

Answer 7

Go Ahead..

Keep it up..
