Can you please explain how to find Domain, Range, Increase, Decrease. For example y=5/x+3

Question

anonymous · Answer

5/x + 3 is just a vertical translation of 5/x 3 units up... so their domain is the same.  their range is different... 5/x range is (-inf, 0) U (0, inf).  so the range for 5/x+3 is (-inf,3) U (3,inf).

increase and decrease intervals are the same for 5/x and 5/x+3...

anonymous · Answer

i'm assuming this is the function y = (5/x) + 3

anonymous · Answer

i think the range is (-inf,0) and (0,nif)

anonymous · Answer

that all depends... 
is your equation y = 5/(x+3) 
or
y = 5/x + 3

anonymous · Answer

oh ok. mine is y=5/(x+3)

anonymous · Answer

if it's the second one, the range is (-inf, 3) U (3, inf)

anonymous · Answer

then forget everything i said....

thank you) what is domain in both cases?
