Problem 437 (difficulty: 1/10)

Formulate the definition using the letters \(\displaystyle \varepsilon,\delta,P,Q\) etc.:

\(\displaystyle \lim_{-\infty}f=1; \quad \lim_{t\to t_0+0}s(t)=0; \quad \lim_{\zeta\to -0}g(\zeta)=-\infty \quad \Olim_{\vartheta\to-1}h(\vartheta)=\infty; \quad \Ulim_{\xi\to-\infty}u(\xi)=2. \)

Give me another random problem!
