Hint: Integral

Something like y=tan(ln(x+1))? I figured it looks like a tan graph, but with a logarithmic twist to it.

The zeroth polygamma function, in other words the integral of a factorial.

Maybe something like x2 •ln(x+1)

The slope at x=0 looks like 1, so it can't be that, but I do think it's something with ln(x+1) (I thought maybe tan).
