us drawing the diagram for you won't help, since we'd use a graphing utility and you won't know what happens. if you have any specific questions about graphing, just say so and i'll try to answer them. otherwise i'll find a from question 2

Now we are told that the graph passes through (2,5), this means when x = 2, y = 5

Hopefully you can take it from here. if not, ask SPECIFIC questions about graphing - May 24th 2007, 02:04 PMJhevon
here's 3

Let

Let

Let

Then we can form via a composite function of f, g and h

Let

As i said, graphing for you won't help, so let's move on to finding the inverse of y

For inverse, we solve for

is the inverse function

As for the graphical relationship. we obtain the graph of the inverse of a function by reflecting the original function in the line
