Q. h(x)=3x11x21 h(x)=\frac{3 x-11}{x^{2}-1} \newlineWe want to find limx1h(x) \lim _{x \rightarrow 1} h(x) .\newlineWhat happens when we use direct substitution?\newlineChoose 11 answer:\newline(A) The limit exists, and we found it!\newline(B) The limit doesn't exist (probably an asymptote).\newline(C) The result is indeterminate.
  1. Direct Substitution: Let's first attempt to use direct substitution to find the limit as xx approaches 11 for the function h(x)=3x11x21h(x)=\frac{3x-11}{x^2-1}. Substitute x=1x = 1 into the function: h(1)=3(1)11(1)21h(1) = \frac{3(1) - 11}{(1)^2 - 1} h(1)=31111h(1) = \frac{3 - 11}{1 - 1} h(1)=80h(1) = \frac{-8}{0}
  2. Substituting x=1x = 1: We observe that the denominator becomes 00, which means the function is undefined at x=1x = 1. This results in a division by zero, which is undefined in mathematics.\newlineSince we have a non-zero numerator and a zero denominator, the result is an indeterminate form.
  3. Undefined at x=1x = 1: The indeterminate form indicates that we cannot determine the limit by direct substitution. We need to use other methods to evaluate the limit, such as factoring, simplifying, or applying L'Hôpital's rule if necessary.\newlineHowever, for the purpose of answering the multiple-choice question, we have enough information to conclude that direct substitution leads to an indeterminate form.
