Well. On the point about modulus. I would sketch without the modulus first and then reflect the graph for y<0 in the x axis.
Your question is not very specific but in general I look for whether I recognise the function and consider x>>0 x<<0 and any singularities.
If I recognise the function I look for f(kx) f(x+a) kf(x) f(x)+k in order to identify transformations.
The way you go about such things is not really formulaic but depends on the question.
