What would be the end behaviors for the polynomial below?

What is the end behavior of the function

• as x →⁻∞,y→⁻∞, as x →∞, y→⁻∞

• as x→⁻∞, y→∞, as x →∞, y→∞

• as x→⁻∞, y→0, as x →∞, y→∞

• as x→⁻∞, y→⁻∞, as x →∞,y→∞

Simplify the expression.
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)

• -8n² - 8n + 3 

• -7n² - 8n + 3 

• -6n² - 8n + 3

• -7n² - 4n + 3

(3x³ + 5x - 1) ÷ (x + 1)

• 3x³ - 3x² + 8x - 9

• 3x² - 3x + 8 - 9/x+1

• 3x² + 3x + 8 + 7/x+1

• 3x³ + 3x² + 8x + 7
