Find the one-sided limit (if it exists). (If the limit is infinite, enter '?' or '-?', as appropriate. If the limit does not otherwise exist, enter DNE.) $\lim_{x \to 0^{-}} \left(5 + \frac{5}{x}\right)$

Find the limits. Write $\infty$ or $-\infty$ where appropriate. $$\lim _{x \rightarrow 0^{-}} \frac{5}{2 x}$$

Let f(x) = { -4/(x+5) if x < -5, 2x + 10 if x > -5. Calculate the following limits. If the limit doesn't exist but it makes sense to call it ∞ enter Infinity , for -∞ enter -Infinity ; in other cases where the limit does not exist enter DNE . lim_{x->-5^-} f(x) = lim_{x->-5^+} f(x) = lim_{x->-5} f(x) =
