Q. Find limx3x35xx32x2+1 \lim _{x \rightarrow \infty} \frac{3 x^{3}-5 x}{x^{3}-2 x^{2}+1} \newlineChoose 11 answer:\newline(A) 5-5\newline(B) 00\newline(C) 33\newline(D) The limit is unbounded
  1. Degree Comparison: To find the limit of the given function as xx approaches infinity, we can compare the degrees of the polynomials in the numerator and the denominator.
  2. Leading Coefficients: The degree of the polynomial in the numerator is 33 (because of the term 3x33x^3), and the degree of the polynomial in the denominator is also 33 (because of the term x3x^3).
  3. Limit Calculation: When the degrees of the polynomials in the numerator and denominator are the same, the limit as xx approaches \infty is the ratio of the leading coefficients.
  4. Limit Calculation: When the degrees of the polynomials in the numerator and denominator are the same, the limit as xx approaches infinity is the ratio of the leading coefficients.The leading coefficient of the numerator is 33 (from the term 3x33x^3), and the leading coefficient of the denominator is 11 (from the term x3x^3).
  5. Limit Calculation: When the degrees of the polynomials in the numerator and denominator are the same, the limit as xx approaches infinity is the ratio of the leading coefficients.The leading coefficient of the numerator is 33 (from the term 3x33x^3), and the leading coefficient of the denominator is 11 (from the term x3x^3).Therefore, the limit as xx approaches infinity of (3x35x)/(x32x2+1)(3x^3 - 5x) / (x^3 - 2x^2 + 1) is 3/13/1, which simplifies to 33.
