Verified Answer :

f(x) = x + 3
y = x + 3
x = y - 3

Inverse is h(x) = x - 3

Answer:

Option C is correct that is h(x)=x-3

Step-by-step explanation:

We have been given a function:

\(f(x)=x=3\)

\(\text{let y}=f(x)\)

\(y=x+3\)

\(x=y-3\)

Hence,\(f^{-1}y=y-3\)

Therefore, \(f^{-1}x=x-3\)

Hence, Option C is correct that is h(x)=x-3
