Question

find the value of ƒ ^-1 (4)

Answer 1

you would need to know the original function

Answer 2

is there a graph? a function?

Answer 3

\[(4) 1/f \] is the answer because you have to use the rule
\[\:a^{-1}=\frac{1}{a}\]
\[f^{-1}=\frac{1}{f}\] =
\[=\left(4\right)\frac{1}{f}\]

Answer 4

I hope this helped!! :}

Answer 5

I think that \(\large\color{#996633}{\displaystyle f^{-1}(4)}\) is a notation for an inverse-function of some function \(\large\color{#996633}{\displaystyle f(x)}\),

evaluated at \(\large\color{#996633}{\displaystyle x=4}\).
