Question

Xplain how the graph of y2 is related to the graph of y1

Answer 1

Y1=1/x-1(+2) y2=1/x+1(-2)

Answer 2

Have you graphed them or at lest found some points like where they intersect and the places they cross the axis?

Answer 3

If you aim for those things, you will find some relationships between the graphs. This should lead you to an answer. The fact that 1/x is involved in both of them is another huge clue, because it means x can never be 0.
