Q. Which statement best describes the limit shown below?x→∞limx73x14The limit equals zeroThe limit does not existThe limit exists and does not equal zero
Given Limit Expression: We are given the limit expression limx→∞(x73x14). To find the limit as x approaches infinity, we need to analyze the behavior of the function.
Simplify by Subtracting Exponents: We can simplify the expression by subtracting the exponents of x in the numerator and the denominator since they have the same base and we are dividing them.limx→∞(x14)/(x73)=limx→∞x14−73
Analysis of Function Behavior: After subtracting the exponents, we get:limx→∞x−59This means that as x approaches infinity, the function is x raised to the power of negative fifty-nine.
Negative Exponent Interpretation: A negative exponent means that the function is the reciprocal of x raised to the positive exponent. Therefore, x−59 is equivalent to 1/(x59).limx→∞x−59=limx→∞1/(x59)
Approaching Zero: As x approaches infinity, the denominator x59 becomes larger and larger, making the whole fraction smaller and smaller, approaching zero.x→∞limx591=0
