Q. Which of the following functions are continuous for all real numbers?g(x)=ln(x)f(x)=x1Choose 1 answer:A) g only(B) f only(C) Both g and fD Neither g nor f
Consider the domain: To determine if g(x)=ln(x) is continuous for all real numbers, we need to consider the domain of the natural logarithm function.
Natural logarithm function: The natural logarithm function ln(x) is defined only for x > 0. Therefore, g(x)=ln(x) is not continuous for all real numbers because it is not defined for x≤0.
Consider the domain: To determine if f(x)=x1 is continuous for all real numbers, we need to consider the domain of the reciprocal function.
Reciprocal function: The function f(x)=x1 is defined for all real numbers except x=0, where the function has a vertical asymptote and is not defined.
Neither g nor f: Since neither g(x)=ln(x) nor f(x)=x1 is continuous for all real numbers, the correct answer is D) Neither g nor f.
