The Correct Answer and Explanation is:
To analyze the rational function G(x) = (x⁴ + 16) / (2x² – 4x) we will determine its vertical, horizontal, and oblique asymptotes.
🔹 Vertical Asymptotes
Vertical asymptotes occur where the denominator is zero and the numerator is nonzero.
Factor the denominator: 2x² – 4x = 2x(x – 2)
Set the denominator equal to zero: 2x(x – 2) = 0 x = 0 or x = 2
Now check the numerator at these x-values: G(0) = (0⁴ + 16) / (0) → undefined G(2) = (2⁴ + 16) / (2(2 – 2)) = 32 / 0 → undefined
Since the numerator is nonzero at both x = 0 and x = 2, these are vertical asymptotes.
✅ Vertical asymptotes: x = 0, 2
🔹 Horizontal Asymptotes
Horizontal asymptotes depend on the degrees of the numerator and denominator.
- Degree of numerator: 4 (from x⁴)
- Degree of denominator: 2 (from 2x²)
Since the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.
✅ Horizontal asymptote: There is no horizontal asymptote
🔹 Oblique Asymptotes
Oblique (slant) asymptotes occur when the degree of the numerator is exactly one more than the degree of the denominator.
Here, the degree of the numerator is 4 and the denominator is 2. The difference is 2, not 1, so there is no oblique asymptote.
✅ Oblique asymptote: There is no oblique asymptote
✍️ Summary
- Vertical asymptotes: x = 0, 2
- Horizontal asymptote: None
- Oblique asymptote: None
This function grows faster in the numerator than the denominator, so it diverges to infinity as x becomes large in magnitude. The vertical asymptotes represent values where the function is undefined due to division by zero. Since the numerator dominates the denominator by more than one degree, the function has neither a horizontal nor an oblique asymptote.
