Let's look at (a).
Can you find g(2) ?

anonymous · Answer

At (0,2)?

mathstudent55 · Answer

What y value does function g have when x = 2?

anonymous · Answer

Would I find 2 on the X axis the go up till I find a point where the line of g intersects at 2? Would it be 5?

mathstudent55 · Answer

Exactly. 
g(2) = 5

mathstudent55 · Answer

Now to finish (a), you need to do f(5).
Find 5 in the x axis, and look up the y value of f(x).

mathstudent55 · Answer

Did you find f(5) ?

anonymous · Answer

Oh I get it! So it would be f(5)=4. So that's all I do. X=the number given for either f or G then when I find the y I then plug that in the remaining problem and find it for g or f. Would c) be rewritten as f(g(0)) where g(0)=2 then f(2)=-2

anonymous · Answer

No sorry counted wrong g(0)=3 then f(3)=0

mathstudent55 · Answer

Exactly.
