MHF4U RATIONAL FUNCTIONS GRAPHING SUMMATIVE ASSIGNMENT 2021 /89 For this assignment you will be asked to sketch graphs of several different functions to demonstrate your understanding of the shape and behavior of quotients of polynomial functions (rational functions). You will be evaluated on the analysis of the functions below and your ability to sketch the graphs accurately. Using a table of values is NOT an acceptable way to graph these functions. This assignment is intended to be done INDIVIDUALLY WITHOUT THE USE OF GRAPHING OR COMPUATIONAL TECHNOLOGY. Please sign below to verify that this is your own work and that you accept the consequences should it be found that you have not completed the work in a manner as stated above.
