Q. Which statement best describes the limit shown below?x→∞lim6x68+x62x68The limit equals zeroThe limit does not existThe limit exists and does not equal zero
Analyze Degree Comparison: We are given the limit expression limx→∞(6x68+x62x68). To find the limit as x approaches infinity, we can compare the degrees of the polynomials in the numerator and the denominator.
Divide by Highest Degree Term: Since the highest degree term in both the numerator and the denominator is x68, we can divide every term by x68 to simplify the expression.x→∞lim6x68+x62x68=x→∞lim6+x68x621
Simplify Expression: Simplify the expression inside the limit by canceling out x62 from the denominator's second term.x→∞lim(6+x68x621)=x→∞lim(6+x611)
Negligible Term Removal: As x approaches infinity, x61 approaches 0. Therefore, the term x61 in the denominator becomes negligible.limx→∞6+x611=limx→∞6+01
Final Simplification: Simplify the expression by removing the term that approaches zero.limx→∞(6+01)=61
Limit Result: The limit of the function as x approaches infinity is 61, which is a finite number and does not equal zero.
