Multiplicity and End Behavior of Polynomials

This is the correct end behavior model for the function
y = (x - 2)²(x² + 1)

• true

• false

These functions have the same end behavior model: y₁ = 3x⁵ + 2x³ + x - 1    and    y₂ = 3x²(2x³ + 4x + 2)

• true

• false

Which of these describes end behavior for the polynomial y = 3x⁵ + 2x³ - 7?

• a

• b

• c

• d

Find the zeros of this polynomial and describe their multiplicity.
f(x) = 3x⁴ - 12x²

• 0 multiplicity 3, -2 multiplicity 1, 2 multiplicity 1

•  -2 multiplicity 1, 2 multiplicity 1

• 0 multiplicity 2, -2 multiplicity 1, 2 multiplicity 1

• 3 multiplicity 4, -12 multiplicity 2
