  1. Identify highest power of x: Identify the highest power of x in the denominator. In this case, the highest power of x in the denominator is x3x^3.
  2. Divide by x3x^3: Divide every term in the numerator and the denominator by x3x^3 to simplify the expression. This gives us 4x2x3\frac{4x^2}{x^3} - 3xx3\frac{3x}{x^3} which simplifies to 4x\frac{4}{x} - 3x3\frac{3}{x^3}.
  3. Evaluate limits: Evaluate the limit of each term as xx approaches infinity. The limit of 4x\frac{4}{x} as xx approaches infinity is 00 because the numerator is constant and the denominator grows without bound. Similarly, the limit of 3x3-\frac{3}{x^3} as xx approaches infinity is also 00 for the same reason.
  4. Combine limits: Combine the limits of the individual terms. Since both terms approach 00, the limit of the entire expression as xx approaches infinity is 00.
