Q. Which statement best describes the limit shown below?\newlinelimx3(2)x5log2x \lim _{x \rightarrow \infty} \frac{-3(2)^{x}}{5 \log _{2} x} \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(3(2)x5log2x)\lim_{x \to \infty}\left(\frac{-3(2)^{x}}{5\log_{2}x}\right). To analyze the behavior of this limit, we need to consider the growth rates of the numerator and the denominator as xx approaches infinity.
  2. Analysis of Growth Rates: The numerator 3(2)x-3(2)^{x} grows exponentially as xx approaches infinity. Exponential functions grow much faster than polynomial or logarithmic functions.
  3. Numerator Behavior: The denominator 5log2x5\log_{2}x is a logarithmic function, which grows much slower than the exponential function in the numerator. As xx approaches infinity, the logarithmic function increases without bound, but at a much slower rate than the exponential function.
  4. Denominator Behavior: Since the numerator grows much faster than the denominator, the fraction as a whole will grow without bound. However, because the numerator is negative, the fraction will tend toward negative infinity.
  5. Limit Conclusion: Therefore, the limit does not exist because the expression diverges to negative infinity. The correct statement is "The limit does not exist."
