Hi mintjellyxd!

 

Question 1

The demoinator of a fraction can't be 0 or negative, so anything less than or equal to -1 will be imposible. 

(-infinity, -1)

 

Question 2

There is no limit to the range of f(x) since x will always get bigger, but the minimum for the square is 0, so the minimum answer is 1.

[1, infinity)

 

I hope this helped. :)))
