1. $lim_{x\rightarrow8}(x^{2}-5x - 11)=$
1. $lim_{x\rightarrow8}(x^{2}-5x - 11)=$
Answer
Explanation:
Step1: Substitute x - value
Substitute (x = 8) into (x^{2}-5x - 11). [8^{2}-5\times8 - 11]
Step2: Calculate powers
Calculate (8^{2}=64). [64-5\times8 - 11]
Step3: Calculate multiplication
Calculate (5\times8 = 40). [64 - 40-11]
Step4: Calculate subtraction
[64-40 = 24], then (24-11=13).
Answer:
