Properties of Polynomial Functions

Based on the end behavior which option best describes the leading term?

• negative coefficient, even degree

• negative coefficient, odd degree

• negative degree, odd coefficient

• negative degree, even coefficient

What are the zeros of the polynomial?

• X=5, x=-3(multiplicity of 2)

• x=-3, x=5(multiplicity of 2)

• x=3, x=-5

• x=5

How many relative extrema(tuning points) are in the picture?

• 2

• 3

• 4

• 5

What is the predicted end behavior of: y=-2x⁴+3x-1

• up on both ends

• down on both ends

• up on left, down on right

• down on left, up on right

What is another way to say "where a function crosses the x-axis"?

• x-intercept

• zero

• root

• all of these.
