Use Definition 1.4.1 to prove that the stated limit is correct. In each case, to show that \(\lim _{x \rightarrow a} f(x)=L\), factor \(|f(x)-L|\) in the form
\(|f(x)-L|=\mid \text { "something }^{\prime \prime}|\cdot| x-a \mid\)
and then bound the size of |”something"| by putting restrictions on the size of \(\delta\)
\(\lim _{x \rightarrow 1} 2 x^{2}=2\)[ Hint: Assume \(\delta \leq 1\). ]
