Consider the function
Solution:
The orbit of
The orbit of
The orbit of
Let
Solution: To find the fixed points we need to solve
Consider the family of functions defined by
Hint: You may end up with different fixed points depending on the
value of
Solution: To find the fixed points of
Consider the function
Use a graphical method (i.e. cobweb diagram) to help determine
the behaviour of various orbits starting near both
Now consider the family of functions
Solution:
From the graph, we can see that
Cobweb diagram:
From our cobweb diagram we see that the iterates of
To find the fixed points of
Let
Solution: First, let’s find any fixed points by solving
Now, let’s find any periodic points of period two. We need to solve
CHALLENGE Let
Solution: First, let’s find the fixed points.
Next, we want to solve for any periodic points of period two. First
we find
CHALLENGE Consider the function
Solution: To find the fixed points of
We can write this as
