Polynomial Functions

1. classify -6x^5+4x^3+3x^2+11 by degree.

A. quintic

B. cubic

C. quartic

D. quadratic

2. write -2x^2(-5x^2+4x^3) in standard form.

A. -8x^5-20x^4

B. -8x^5+10x^4

C. -7x+2x^4

D. -7x^5-10x^4

3. Consider the leading term of the polynomial function. What is the end behavior of the graph? 2x^7-8x^6-3x^5-3

A. The leading term is 2x^7. Since n is odd and a is positive, the end behavior is up and up.

B. The leading term is 2x^7. Since n is odd and a is positive, the end behavior is down and down.

C. The leading term is 2x^7. Since n is odd and a is positive, the end behavior is down and up.

D. The leading term is 2x^7. Since n is odd and a is positive, the end behavior is up and down.

4. Graph y=2x-x^3. How many turning points are there?

A. There are two turning points.

B. There are no turning points
