and also, if - inf/ some # ...does that always equal inf?

No, because ln(e)=1 and that does not equal plus or minus infinity.

graph of lnx varies from -inf 2 +inf. so lnx can take any value for range but domain (x>0) should be positive

???
I'm not really sure I understand the question. The natural logarithm of a number is the value to which e (the base of the natural logarithms) must be raised to equal the number.

for y= ln(x)
the domain that is the x value must be
0
the range that is the y value must be
-infinity < y=ln(x) <+infinity
