MHF 4U Learning Goals and Success Criteria
Unit 2a: Graphing Polynomial and Rational Functions
Learning Goal
I will be able to:
• Describe key features of polynomial functions and make connections between
representations of them. (PR1)
• Describe key features of the graphs of rational functions and represent them
graphically. (PR2)
Success Criteria
I can:
• Compare the numeric, graphical and algebraic representations of polynomial
functions. (PR1)
• Describe key features of graphs of polynomial functions. (PR1)
• Distinguish polynomial functions from graphs of other types of functions. (PR1)
• Determine the roles of a, k, d, and c in transforming graphs of cubic and quartic
functions. (PR1)
• Determine an equation of a polynomial function or family of polynomial functions
that satisfies a given set of conditions. (PR1)
• Compare the properties of even and odd degree polynomial functions, and identify
polynomial functions as even, odd or neither. (PR1)
• Determine the key features of the graphs of reciprocal functions and make
connections between the algebraic and graphical representations of the functions.
(PR2)
• Determine key features of rational functions that have linear expressions in the
numerator and denominator and make connections between the graphical and
algebraic representations of the functions. (PR2)
• Sketch the graph of a simple rational function using key features given the equation
for the function. (PR2)
Test Information:
Your test is Thursday, March 8th. You can come in during lunch if you think that you might
need a bit of extra time. I will allow you to start writing at 11:20. You should not NEED extra
time, but you are welcome to take it if it will make you feel less stressed!
There is a more detailed test outline on the back of this sheet. These are the types of
questions you can expect. To prepare well for this test, you should (in this order):
• Review your notes, and makes study notes. We talked about a lot of theory, so be
sure that you actually understand it!
• Review/redo your quizzes and go through the examples in the notes and be sure that
you can do them yourself.
• Complete questions in the suggested review that you think you need to do. The text
book should be your last stop, not your first!
If you need help with anything, please contact me through Edsby, Remind, or email, or
come in at lunch or before school on Wednesday!
