# Good old functions!! watch

1. I have done the first part, stuck on the other parts.

The function g(x)= 2x+5 / x-1, where XER and x>1

a) Find the inverse function, which is (x+5)/(x-2), this is correct

b) Determine the range of the inverse function
c) Determine the domain of the inverse function.

I know that the range means like what values it must be above, and the domain is what value you can input into the function, just can't 'determine' them.
2. b)

range of inverse is domain of the original, which is given.

c)

domain of inverse is range of original, which is from infinity (when x is ever so slightly bigger than one), to 2 = when x is big (since the integers being added and subtracted become insignificant).
