Question 990586: 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

You can put this solution on YOUR website! 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.
