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

find the value if f(x)=5/x+2 and g(x)=-2x+3
1.)f(-4)
2.)g(1/2
3.)g(-6)
4.)f(m-2)
f(x) is AMBIGUOUS! Needs parentheses!

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.
