This video will summaries today's objectives: identifying odd and even functions, and determining their end behaviors.

Can you look at a graph of a polynomial to determine whether it is odd or even? Explain?

Multiple Select

Draw a polynomial such that...

• It is even

• It is negative

• Has a zero at x=-2 and x=4

• Has a y-intercept at (0,3).

Open Ended

Draw a polynomial that is odd, negative, with only one zero at x = 6. Describe its end behavior.

Now, go to www.desmos.com and graph

 $y=-2x^3-x$ .  Describe the tails? Is this graph negative or positive? Is the function odd or even?

Watch this video on the end behavior of graph's of polynomials.

If the tails are pointing in the same direction, is the polynomial odd or even?
