It's definitely a typo, you can't turn a quadratic into a linear expression by multiplying and adding constants, assuming a, b and c are just constants.
4. I would try to help you but I failed my exam :/

g(2x) just means replace every x from g(x) with (2x)
so you get

g(2x) = (2x + 6) / 4x

Now the problem is very similar to the first part of the problem
