Exercise 29.3
Evaluate the following limits: \[\underset{x\to 2}{\mathop{\lim }}\,\frac{{{x}^{3}}-8}{{{x}^{2}}-4}\]
Evaluate the following limits: \[\underset{x\to 3}{\mathop{\lim }}\,\frac{{{x}^{4}}-81}{{{x}^{2}}-9}\]
Evaluate the following limits: \[\underset{x\to 3}{\mathop{\lim }}\,\frac{{{x}^{2}}-4x+3}{{{x}^{2}}-2x-3}\]
∴ The value of the given limit is \[1/2\]
