You can put this solution on YOUR website! Assuming f(x) = 5/(x+2) is what you intended...
1.) f(-4) = 5/ (-4+2) = 5/(-2) = -5/2, as a decimal that's -2.5
2.) g(1/2) = -2(1/2) + 3 = ______
and similar for the others, in #4, you need to plug in x=m-2

You can put this solution on YOUR website! .
Regarding parts 1), 2), 3), I do not see any realistic reason
why any ordinary student can not do it on his (or her) own.
The only explanation which comes to my mind is that this person does not want to make his (or her) work, at all,
and wants the tutors perform his (or her) duties.
My view is that such attempts should be  immediately at this forum at first appearance.
