Chapter 1, Problem 29(choose chapter or problem)
(a) Show that
\(\left|\left(3 x^{2}+2 x-20\right)-300\right|=|3 x+32|+|x-10|\)
(b) Find an upper bound for \(|3 x+32|\) if x satisfies \(|x-||0|=1\)
(c) Fill in the blanks to complete a proof that
\(\lim _{x \rightarrow 10}\left[3 x^{2}+2 x-20\right]=300\)
Suppose that \(e=0\). Set \(\delta=\min\) (1,_________) and assume that \(0=|x-10|=\delta\). Then
\(\left|\left(3 x^{2}+2 x-20\right)-300\right|=|3 x+32| \cdot|x-10|\)
< _________ \(\cdot|x-10|\) < _________\(\cdot\)_________ \(=\epsilon\)
