It is Assumed the logarithm given are to base 10.
y=log5(x−1)+3
it's Domain
For the log to be positive x>1
(1,∞)
Range
All real numbers
(−∞,∞)
x-intercept
log 5(x−1)+3=0
log5(x−1)=−3
5x−5=0.001
x=1.0002
(1.0002,0)
Zeros
At y=0
x=1.0002
Vertical Asymptote
For 5(x−1)>0
x>1
Asymptote is x=1
y=log(3x−2)
Domain
For log to be positive 3x−2>0⟹x>32
(32,∞)
Range
All real values
