1. y = 3x^2 - 7x^4 + 9 - x^4 2. y = (t - 2)(t + 1)(t + 1)
NO polynomial has an asymptote! 3x^2 - 7x^4 + 9 - x^4 = -8x^4 + 3x^2 + 9 degree: 4; number of terms: 3 y → -∞ as x → ±∞ (t - 2)(t + 1)(t + 1) = t^3 - 3t - 2 y → -∞ as x → -∞ y → +∞ as x → +∞ degree: 3; number of terms: 3
2. y = t^3 - t; degree: 3; number of terms: 3; end behavior: asymptote at x = -1 and x = 2.
