Soit f, colon, x, ↦, start fraction, 3, divided by, x, end fraction.

Les limites de f en 0, start superscript, plus, end superscript et en 0, start superscript, minus, end superscript sont :

(Choix A)
limit, start subscript, x, \to, 0, start superscript, plus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, plus, infinity et limit, start subscript, x, \to, 0, start superscript, minus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, plus, infinity
(Choix B)
limit, start subscript, x, \to, 0, start superscript, plus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, plus, infinity et limit, start subscript, x, \to, 0, start superscript, minus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, minus, infinity
(Choix C)
limit, start subscript, x, \to, 0, start superscript, plus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, minus, infinity et limit, start subscript, x, \to, 0, start superscript, minus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, plus, infinity
(Choix D)
limit, start subscript, x, \to, 0, start superscript, plus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, minus, infinity et limit, start subscript, x, \to, 0, start superscript, minus, end superscript, end subscript, f, left parenthesis, x, right parenthesis, equals, minus, infinity
