Q. Which statement best describes the limit shown below?\newlinelimx9x5610ex10x97 \lim _{x \rightarrow \infty} \frac{9 x^{56}}{-10 e^{x}-10 x^{97}} \newlineThe limit equals zero\newlineThe limit does not exist\newlineThe limit exists and does not equal zero
  1. Analyze Behavior as xx Approaches Infinity: We need to analyze the behavior of the function as xx approaches infinity. To do this, we look at the degrees of the polynomial in the numerator and the terms in the denominator.
  2. Degree of Numerator and Denominator: The numerator is 9x569x^{56}, which is a polynomial of degree 5656. The denominator is 10ex10x97-10e^{x}-10x^{97}, which contains an exponential function exe^{x} and a polynomial of degree 9797.
  3. Exponential Function Dominance: As xx approaches infinity, the exponential function exe^{x} grows much faster than any polynomial. Therefore, the term 10ex-10e^{x} in the denominator will dominate over the 10x97-10x^{97} term.
  4. Denominator Grows Faster: Since the exponential function grows faster than any power of xx, the denominator will grow much faster than the numerator as xx approaches infinity. This means that the fraction as a whole will approach zero.
  5. Limit as x Approaches Infinity: Therefore, the limit of 9x5610ex10x97\frac{9x^{56}}{-10e^{x}-10x^{97}} as x approaches infinity is 00.
