Basic Polynomial Functions

What are the approximate zeros of the function?

• 4,1

• 3,1,-2,-5

• -3, -1, 2, 5

• -2,4

f(x)= x²(x – 2)³(x – 7)

Find and select each real zero and its multiplicity

• 0 (Mult of 2), 2 (Mult of 3), 7 (mult 1)

• 2 (Mult of 3), 7 (mult 1)

• 0, 2, 7

• 2 (mult of 2), 7 (mult of 3)

Please select the solution that describes if zeros crosses or turns at the x-axis for each x-intercept.

• x=2 crosses, x=1 crosses, x= -3 turns, x = -4 turns

• x=1 crosses, x = -3 turns, x= - 4 crosses

• x= 1 crosses, x= -3 turns, x= -4 turns

• x= 1 turns, x= -3 crosses, x= -4 crosses

f(x)=(x+4)(x-3)(x-2)
List the zeros for this function.

• x = -4, x = 3, x = -2

• x = -4, x = 3, x = 2 

• x = -4, x = -3, x = 2

• x = 4, x = 3, x = 2

What is the degree of f(x)?

• 3

• 2

• 1

• 0

If a zero of a polynomial function has multiplicity 4 that means:

• The x intercept is at (4, 0)

• The graph will "bounce back" at that zero

• The graph will "pass through" at that zero

• Zeros cannot have multiplicity of 4

Describe the end behavior of the function.
y = 4x¹⁰

• down and down

• down and up

• up and down

• up and up

Describe the end behavior of the function.

y = -6x + 4 + 9x³

• Left down Right down

• Left down Right up

• Left up Right down
