Is that $$\ln x^{2}$$ ot $$(\ln x)^{2}$$ ??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 $\ln x$ looks like, you can easily graph $\ln x^2$, since $\ln x^2=2\ln x$.

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

If you don't know what $e^x$ looks like..., well you should.
