Question

F and f^-1 are functions
If f(4)=2, then f^-1(2)=?​

Answer 1

Step-by-step Answer:

f and f^(-1) are inverses of each other within a specified domain, with the property that

y=f(x) <=> (is equivalent to) f^(-1)(y)=x

since

2=f(4), by the definition of inverse functions, f^(-1)(2) = 4

Answer 2

-4, -2, -2 hope that will help you
