Learning Intention:

Unit 3 module 5.4Part 2

Graphing Polynomial Functions

Given a polynomial function students will be able to use the zero product property to graph the intercepts of the function and identifying the end behavior.

Success CriteriaI will be able to identify the x­intercepts in a polynomial in factored form. 

I will be able to sketch a polynomial in factored form. I will be able to identify the end behavior of a polynomial function. 

Sketch the graph of the polynomial function.

Example

How many distinct factors are there?

What are the x­intercepts?

What are the y­intercepts?

What is the end­behavior?

Tangent to the x­axis:

Multiplicity:

Turning points:

Relative max

Relative min:

Standard form:

Use desmos to graph

What do you observe happens at the even power factors?

What do you predict will happen at the odd power factors?

What do you observe happens at the odd power factors?

ExampleSketch a graph of the polynomial function.f(x)=(x­2)3(x­5)2

How do you find the degree of the polynomial? What happens if we have a binomial square? Tripled? Quadrupled? Quintuple?
