Substitution of x: To find the limit as x approaches 1, we can directly substitute x with 1 in the expression (x−11)/(x+7), since the denominator does not become zero and there is no indeterminate form.
Arithmetic calculation: Substitute x=1 into the expression: limx→1x+7x−11=1+71−11
Fraction simplification: Perform the arithmetic: (1−11)/(1+7)=(−10)/8
Final answer: Simplify the fraction: (−10)/8=−5/4
Final answer: Simplify the fraction: (−10)/8=−5/4 The simplified fraction −5/4 corresponds to answer choice (B).
