A) 0
B) 5
C) 10
D) 25
Correct Answer: A
Solution :
\[f(5)=\underset{x\to 5}{\mathop{\text{lim}}}\,f(x)\]\[=\underset{x\to 5}{\mathop{\text{lim}}}\,\frac{{{x}^{2}}-10x+25}{{{x}^{2}}-7x+10}\] \[=\underset{x\to 5}{\mathop{\text{lim}}}\,\frac{{{(x-5)}^{2}}}{(x-2)(x-5)}=\frac{5-5}{5-2}=0\].You need to login to perform this action.
