Other answers:

You have to understand what f(x) means, which is?
Function notation ?
Yes...but what does it say about x?
Replace it with -1
Yes, in your question do it first with the function g(-1)
Wait so what am I doing ..? I'm sorry I don't understand any of this ..
Start first within the innermost parentheses of $$\huge f(g(x))$$ and work towards the outermost parentheses ...
I know that much I just don't know how to solve it or work it out
|dw:1378321409759:dw|
I thought so . But I wasn't sure if -1 went in g(x) ..
Now what?
Do we work out f(x) ..?
Yes.
Replace "x" with -1 ?
We use the result from g(-1) in f. That is what f(g(x)) means...
Okay so 2 then .
That would be 5 then
f(x)=5x-10
Yes , isn't the answer 5 ?
How?

Excuse me? Are you trying to troll me with $$\huge5(2)=25$$
No ?? I thought that's that you had to do .. Sorry ...
what *
|dw:1378322275977:dw|
I already warned you that I didn't know how to do any of this .
Ok I know .
so what is 5*2=?
25 I know . I understand that .
I mean 10 sorry
I just kidding about the trolling :D so what is your answer?
Ok . It's 10
correct your work please
What ?
|dw:1378322533506:dw|
It's not worth correcting though , I already know the answer . So is 10 the answer to the entire question ?
Or just for f(x)
|dw:1378322646531:dw|
f(g(x)) = 0 when x = -1
Okay
Okay thank you
|dw:1378322937548:dw|
What about this one ?
What about it?
Nevermind I'm just going to guess . I don't have enough time to work out all of these problems . Thanks for your help though .
I can help if you want to learn :-)
It is the same as the last one we did ...
Just let x=15
I do want to learn but I'm being timed . I'm taking a quiz . I don't have time to work out anything else ....
start from the innermost function
I tried working it out , is it 16 ? Yes or no :o
Ugh .. That was my second choice -.-
Go.od luck, come back and learn when you have time
Okay
