    Is that [tex] \ln x^{2} [/tex] ot [tex] (\ln x)^{2} [/tex] ??If so,why don't u graph it??Do u know how??

    it is lnx^2 (the first one) and i can't graph it. i don't know how. i've found all of the info ex. domain, asymptotes,intervals of increase/decrease, local min/max, concavity, and Inflection points

    i can do those steps but have difficulty graphing functions

    (and no graphing calc to check solutions)

    If you know what [itex]\ln x[/itex] looks like, you can easily graph [itex]\ln x^2[/itex], since [itex]\ln x^2=2\ln x[/itex].

    If you don't know what [itex]\ln x[/itex] looks like, it's the graph of [itex]e^x[/itex] when mirrored through the line y=x, because they are the inverse functions of each other.

    If you don't know what [itex]e^x[/itex] looks like..., well you should.
