Oblicz granice lim dazy do x->5- [latex] frac{3}{x-5} [/latex] b)lim dazy do x->0+ [latex] frac{x-1}{x} [/latex] c) lim dazy do x->4- [latex] frac{x}{4-x} [/latex]

[latex] lim_{x o 5} - frac{3}{x-5}= - frac{3}{5-5}= - frac{3}{0}= oxed{-infty} \ \ \ lim_{x o 0} + frac{x-1}{x} = + frac{0-1}{0}= frac{-1}{0}= oxed{-infty} \ \ \ lim_{x o 4} - frac{x}{4-x} =- frac{4}{4-4} =- frac{4}{0} =oxed{-infty} [/latex]
