Please help with the questions highlighted in yellow.

For aiii) I don't know how to find the range of this function.

for di) I don't know the technique or method to graph an absolute function -- please give me some general techniques on how to do this.

for diii), it's the same problem as that with dii). The mark scheme says it can be solved by drawing the graphs of of h(x) and g(x) deducing the answer from them. But again, I don't know how to draw them.

NO GDC ALLOWED.

The range of the function is the set of the answers. For quick solutions, just do this:
f(x)
domain:a<x<b
range:f(a)<f(x)<f(b)
Absolute functions is just like a normal function except that all the negs values of f(x) gets inverted. like this: |dw:1352888600412:dw|
