I'm back again... this time with a new question.

How would we read this graph? Do we have to find the equation for f(x) and g(x)?

Am I missing something? I keep getting -8 but according to the thing, it's wrong? Unless that's the correct answer and I'm not going crazy.

[quote=tsubasa128]No you just find the value of them. What's g(-2) according to the graph?
After you find the number you plug in the that number into f(x). Then you find the answer of that by looking at the graph again.[/quote]
This. So for example if it was asking for f(g(0)), you're finding for f(8) because g(0) = 8.
