# Lire la représentation graphique d'une fonction en escalier

## Problème

A coordinate plane. The x- and y-axes both scale by one. The graph is of function y equals g of x which is a series of three horizontal line segments. The first segment starts with an open point at negative nine, negative nine and ends with a closed point at negative five, negative nine. The second segment starts with an open point at negative five, six and ends with a closed point at negative one, six. The last segment starts with an open point at negative one, negative seven and ends with a closed point at nine, negative seven.
Les associations correctes sont :
$-9$minus, 9 $g(-5{,}0001)$g, left parenthesis, minus, 5, comma, 0001, right parenthesis $g(-5)$g, left parenthesis, minus, 5, right parenthesis $g(-4{,}999)$g, left parenthesis, minus, 4, comma, 999, right parenthesis $g(9)$g, left parenthesis, 9, right parenthesis
