Answer:
[tex]{f}^{ - 1} (f(93)) = 93[/tex]
[tex]f(f(7)) = - 15[/tex]
Step-by-step explanation:
A function and its inverse has the following properties
[tex] {f}^{ - 1} (f(x)) = x[/tex]
This implies that;
[tex] {f}^{ - 1} (f(93)) = 93[/tex]
From the table,
[tex]f(7) = - 6[/tex]
This means that:
[tex]f(f(7)) = f( - 6)[/tex]
[tex]f(f(7)) = - 15[/tex]
Note that: f(7) means the value of f(x) when x=7.
From the table f(x)=-6 when x=7.
That is why f(7)=-6.
