State the number of real zeros.

• 1

• 2

• 3

• 4

Is the leading coefficient positive or negative?

• Positive

• Negative

Is the function even or odd?

• Even

• Odd

What is the degree of the function:

f(x) = 6x² + 4 - 3x⁴ + 5x - 9x³

• 1

• 2

• 3

• 4

What type of function is:

f(x) = 6x² + 4 - 3x⁴ + 5x - 9x³

• linear

• quadratic

• cubic

• quartic

A function with degree 3 is called

• constant

• cubic

• linear

• quadratic

If f(x) = 4x³ + 5x² - 3, find f(-2).

• -415

• -15

• -55

• -615

Simplify:

(4x³ + 2x² - 5x - 9) + (-3x³ - 5x² - x + 11)

• 7x³ + 7x² - 6x + 2

• x³ - 3x² - 6x + 2

• 7x³ - 3x² - 6x + 2

• x³ + 7x² - 4x + 2

Simplify:

(4x³ + 2x² - 5x - 9) - (-3x³ - 5x² - x + 11)

• 7x³ + 7x² - 4x - 20

• 7x³ - 3x² - 6x + 2

• x³ - 3x² - 6x + 2

• x³ + 7x² - 4x - 20

Simplify: (x - 5)²

• x² - 25

• x² + 25

• x² - 10x + 25

• x² - 5x - 25
