Q. Which statement best describes the limit shown below?\newlinelimxx762(2)x+3x76 \lim _{x \rightarrow \infty} \frac{x^{76}}{2(2)^{x}+3 x^{76}} \newlineThe limit equals zero\newlineThe limit does not exist\newlineThe limit exists and does not equal zero
  1. Given Limit Expression: We are given the limit expression limx(x762(2)x+3x76)\lim_{x \to \infty}\left(\frac{x^{76}}{2(2)^{x}+3x^{76}}\right). To find the limit as xx approaches infinity, we need to analyze the behavior of the numerator and the denominator separately.
  2. Analyze Numerator: The numerator is x76x^{76}, which grows very large as xx approaches infinity. However, we need to compare this growth with the growth of the denominator to determine the limit.
  3. Analyze Denominator: The denominator is 2(2)x+3x762(2)^{x} + 3x^{76}. The term 2(2)x2(2)^{x} grows exponentially as xx approaches infinity, which is much faster than the polynomial growth of x76x^{76}. Therefore, the exponential term will dominate the denominator as xx becomes very large.
  4. Comparison of Growth: Since the exponential growth in the denominator is much faster than the polynomial growth in the numerator, the fraction as a whole will approach 00 as xx approaches infinity. This is because the denominator will become much larger than the numerator.
  5. Final Limit: Therefore, the limit of the function as xx approaches \infty is 00. This means that the statement "The limit equals zero" best describes the limit of the given function.
