Examples

Example 1: Positive Infinity Limitf(x)=3x4,x+f(x) = 3x^4, \quad x \to +\inftyf(x)=3×4,x→+∞

  • Coefficient: 3
  • Power: 4
  • Direction: x → +∞

Result:

Explanation: Since the exponent is positive and the coefficient is positive, the function increases without bound as xxx approaches +∞.


Example 2: Negative Infinity Limit with Odd Powerf(x)=2x3,xf(x) = -2x^3, \quad x \to -\inftyf(x)=−2×3,x→−∞

  • Coefficient: -2
  • Power: 3
  • Direction: x → -∞

Result:

Explanation: The exponent is odd and the coefficient is negative. As xxx becomes a large negative number, the negative cube flips the sign, resulting in a positive infinity.


Example 3: Zero Powerf(x)=5x0,xf(x) = 5x^0, \quad x \to \inftyf(x)=5×0,x→∞

  • Coefficient: 5
  • Power: 0
  • Direction: x → +∞

Result: 5

Explanation: Any number to the power of zero is 1. Multiplying by the coefficient gives the finite limit 5.


Example 4: Negative Powerf(x)=7x2,x+f(x) = 7x^{-2}, \quad x \to +\inftyf(x)=7x−2,x→+∞

Result: 0

Explanation: A negative exponent represents a fraction with x in the denominator. As xxx approaches infinity, the fraction tends to zero.
