Question

Which answer pairs a possible domain restriction for f(x) and its corresponding impact on f-1(x)

Answer 1

Answer:

B. f(x) domain: x ≥ 1

f–1(x) range: y ≥ 1

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

Because the two functions are inverse to each other, so we all know that the domain of f(x) will be the range of $f^{-1} (x)$ and the range of  f(x) will be the domain of  $f^{-1} (x)$

As can be seen from the attached photo,  

f(x) extends to the right of x=1, so its domain is x ≥ 1.

<=> $f^{-1} (x)$ range is y≥ 1.

Therefore, we choose answer B

Hope it will find you well.
