Select the correct description of right-hand and left-hand behavior of the graph of the

polynomial function.

?(x) = 4x2 - 5x + 4

Falls to the left, rises to the right.

Falls to the left, falls to the right.

Rises to the left, rises to the right.

Rises to the left, falls to the right.

Falls to the left.

QUESTION 2

Describe the right-hand and the left-hand behavior of the graph of

t(x) = 4x5 - 7x3 - 13

Because the degree is odd and the leading coefficient is positive, the graph falls to

the left and rises to the right.

Because the degree is odd and the leading coefficient is positive, the graph rises to

the left and rises to the right.

Because the degree is odd and the leading coefficient is positive, the graph falls to

the left and falls to the right.

Because the degree is odd and the leading coefficient is positive, the graph rises to

the left and falls to the right.

Because the degree is even and the leading coefficient is positive, the graph rises

to the left and rises to the right.

QUESTION 3

Select the correct description of right-hand and left-hand behavior of the graph of the

polynomial function.

?(x) = 3 - 5x + 3x2 - 5x3

Falls to the left, rises to the right.

Falls to the left, falls to the right.

Rises to the left, rises to the right.

Falls to the left.

QUESTION 4

Select from the following which is the polynomial function that has the given zeroes.

2,-6

f(x) = x2 - 4x + 12

f(x) = x2 + 4x + 12

f(x) = -x2 -4x - 12

f(x) = -x2 + 4x - 12

f(x) = x2 + 4x - 12

QUESTION 5

Select from the following which is the polynomial function that has the given zeroes.

0,-2,-4

f(x) = -x3 + 6x2 + 8x

f(x) = x3 - 6x2 + 8x

f(x) = x3 + 6x2 + 8x

f(x) = x3 - 6x2 - 8x

f(x) = x3 + 6x2 - 8x

3x2 - 6x + 9, x ? 6

3x2 - 6x - 9, x ? 6

3x2 + 6x + 9, x ? 6

QUESTION 12

Use synthetic division to divide:

(x3 - 27x + 54) ÷ (x - 3)

x2 + 3x - 18, x ? 3

x2 - 3x - 27, x ? 3

x2 + 9x + 18, x ? 3

x2 + 9x - 6, x ? 3
