Phrasal Verbs group defined by this website

Dear Teacher,

I am studying phrasal verbs in this website, it is very good! I have only one question here. I just do not really intransitive verbs which is defined that they do not take an object, but why like "bring forth","bring in" etc in this website, they take an object, for example:
The job brings in two thousand dollars a month.
She brought forth a surprising result.

Thank you in advance.

Think of the second word in the verb as a vector or direction: forth=forward, in=inside, up=upwards, etc.
