Q. Which statement best describes the limit shown below?x→∞limlog4x+4xx37The limit equals zeroThe limit does not existThe limit exists and does not equal zero
Analyze Function Behavior: We need to analyze the behavior of the function log4(x)+4xx37 as x approaches infinity. To do this, we will compare the growth rates of the numerator and the denominator.
Numerator Growth Rate: The numerator x37 is a polynomial function of degree 37, which grows very quickly as x becomes large.
Denominator Comparison: The denominator is the sum of log4(x) and 4x. The logarithmic function log4(x) grows slowly compared to the exponential function 4x. Therefore, as x approaches infinity, the 4x term will dominate the denominator.
Dominant Term: Since the exponential function 4x grows much faster than the polynomial function x37, the denominator will increase much more rapidly than the numerator as x approaches infinity.
Approaching Infinity: As a result, the fraction(x37)/(log4(x)+4x) will approach zero because the numerator becomes insignificant compared to the rapidly increasing denominator.
Limit Statement: Therefore, the correct statement that describes the limit is: "The limit equals 0."
