Hi!
I can tell the domain from the graph of these functions but how do I tell the range from their graphs?
and
I can find the domain easily:
Also, why does the graph of flip over the x-axis and the graph of flip over the y-axis?

Think about the transformations to a function f(x). -f(x) is a reflection over the x-axis while f(-x) is a reflection over the y-axis.
As for working out the range, for a standard function , the range is . Why? Now what transformations have been applied and how does this affect the range?
