SOLUTION: I'm trying to find the domain and range of the equation y=2x-3 and of the inverse function, y= x+3/2 I think you have to set the domain of the inverse one to zero but I'm not sure,

I'm trying to find the domain and range of the equation y=2x-3 and of the inverse function, y= (x+3)/2 I think you have to set the domain of the inverse one to zero but I'm not sure, may you please help me. Thank You
----------
y = 2x-3
Domain:: All Real Numbers
Range:: All Real Numbers
-----------
y = (x+3)/2 = (1/2)x + (3/2)
Domain:: All Real Numbers
Range:: All Real Numbers
-----
Thinking about Domain::
Start with the idea that Domain is All Real Numbers
Limit that be looking for variables in even-root expressions,
or variables in log or ln expressions, variables in denominators.
If you can't find any of those limits, the Domain IS All Real Numbers.
------
Thinking about Range::
That's the set of all values produced by the Rule when
the Domain values are applied.
