$f:\mathbb{R}_+\to \mathbb{R}_+, f(x)=\log(x+1)$
How to start? Should i start computing $f(1), f(2) ....$ and then plotting them on the graph

Basically we have a set of positive real numbers as the domain and same for codomain. It is certainly a one one function as in log graph every value of x will give a unique y value.(Plot and SEE!) This function will also be onto as all real numbers on the x axis will give a different y value as the graph is not symmetrical and is always increasing .So also onto. Hope you get the idea :)
