1. From the function f (x)=IxI How would I go about finding its image set using interval notation?

2. Again using interval notation, how would I go about finding the image set of the graph g(x)= Ix+3I -2 ? And how then would I go on to solve the equation g(x)=1, and discover if it had any geometrical significance?

3. How would I go about finding if there was solution to the equation g(x)=-4?
