what is the limit? lim x→−3 √(x² - 8) 1 √(-14) -5 √2

what is the limit? lim x→−3 √(x² - 8) 1 √(-14) -5 √2
Answer
Explanation:
Step1: Substitute x value
Substitute $x = - 3$ into $x^{2}-8$. So we get $(-3)^{2}-8$.
Step2: Calculate expression value
$(-3)^{2}-8=9 - 8=1$.
Step3: Find square - root
$\lim_{x\rightarrow - 3}\sqrt{x^{2}-8}=\sqrt{(-3)^{2}-8}=\sqrt{1}=1$.
