As per the given value of the function , value of [tex]f^{-1}(3) = 2[/tex] and [tex]f^{-1}(8) = 7[/tex].
What is function?
" Function is defined as the for each input value there is one and only one output."
According to the question,
From the given table value of function [tex]f(x)[/tex]defined for [tex]x[/tex]
Consider,
[tex]f(x) = y\\\\\implies x = f^{-1}(y)[/tex]
Value of required function we get,
[tex]y= 3\\\\\implies f^{-1}(3)= 2[/tex]
[tex]y= 8\\\\\implies f^{-1}(8)= 7[/tex]
Hence, as per the given value of the function , value of [tex]f^{-1}(3) = 2[/tex] and [tex]f^{-1}(8) = 7[/tex].
