That does not seem right to me because when i graph it, they turn out different.

I am using the 3 major laws of logs

logA + logB = log(AB)

logA - logB = log(A/B)

nlogA = log (A^n)

so again...

2logx-log4-log3+logx

= log(x^2) -log4-log3 + logx

= log((x^2)(x)/((3)(4))

= log (x^3/12)

You must be graphing it incorrrectly.
