Polynomial Functions 
Polynomial Functions
TLW be given a polynomial function and be assessed on the use of the calcultor to find the following. . TLW state the degree of the expression and determine if it is an odd/even degree. TLW state the leading coefficient and determine if its pos/neg. TLW identify roots and location principle. TLW state all max and min. TLW classify the end behavior. TLW draw the graph from what it looks like from calculator. HOT . . TLW develope their own polynomial function of each type, constant, linear, quadratic, cubic, quartic.

Degree & Leading Coefficient

Excellent

My answer shows I successfully dissected and labeled the degree of the function and stated whether it is even/odd. My answer correctly states the leading coefficient, verifing its sign.
Good

My answer shows I stated all four concepts that was asked of me and more than half were correct.
Fair

My answer shows less than the four concepts asked of me were stated and all anwers given were correct.
Poor

My answer shows less than the four concepts asked of me were stated and some or all answers were incorrect.
Roots & Location Principle

Excellent

My answer justifies that I know how to use the graphing calculator to locate all roots, accurate to two decimal places. My answer shows I successfully know how to determine consecutive values of x between which each real zero is located and it correlates to the roots stated previously.
Good

My answer justifies that I know how to use the graphing calculator to locate some roots, accurate to two decimal places. My answer shows I successfully know how to determine consecutive values of x between which the stated real zero is located and it correlates to the roots stated previously.
Fair

My answer justifies that I know how to use the graphing calculator to locate some roots, accurate to two decimal places. My answer shows I did not know how to determine consecutive values of x between which each real zero is located.
Poor

My answer shows I do not know how to find the roots using my calcultor and could not interpret the Location Principle.
Max & Mins

Excellent

My answer justifies that I know how to use the graphing calculator to locate all max and mins, and state the accurate ordered pair, (x,y), to two decimal places.
Good

My answer justifies that I know how to use the graphing calculator to locate all max and mins, but could not state the accurate ordered pair to two decimal places.
Fair

My answer justifies that I know how to use the graphing calculator to locate some max or mins, and can state the accurate ordered pair to two decimal places.
Poor

My answer shows I do not know how to use the graphing calculator to locate the max or mins and could not state the accurate ordered pair to two decimal places.
End Behavior

Excellent

My answer correctly identifies the end behavior. I have correctly stated what f(x) and x approaches on the left side of the graph and what f(x) and x approaches on the right side of the graph.
Good

My answer correctly identifies more than half of the end behavior.
Fair

My answer correctly identifies only half of the end behavior.
Poor

My answer identifies less than half of the end behavior correctly or none of the end behavior.
My graph

Excellent
Good

The sketch of my graph accurately models the polynomial function given which shows I know how to graph a function using my graphing calculator.
Fair

The sketch of my graph does not model the polynomial function correctly which shows I do not know how to graph a function using my graphing calculator.
Poor

I did not draw a graph.
Develop my own polynomial function

Excellent

My answer shows I can create a polynomial function which shows I portray mastery in writing an expression to match the type of polynomial asked for.
Good

My answer shows I can correctly establish a polynomial function that has most aspects involved in creating the expression, correct.
Fair

My answer shows I can establish a polynomial function that has half aspects the involved in creating an expression, correct.
Poor

My answers shows I can not create a polynomial function correctly.
