                                                                                           两竿落日溪桥上，半缕轻烟柳影中。
                                                                                           多少绿荷相倚恨，一时回首背西风。
                                                                                                             暮热游荷池上
                                                                                                            （宋）杨万里

                                                                                             荷花入暮犹愁热，低面深藏碧伞中。

已知偶函数f（x）的定义域为{x|x∈R且x≠0}，f（x）=$\left\{\begin{array}{c}{2}^{\left|x-1\right|}-1,0<x\le 2\\ \frac{1}{2}f\left(x-2\right),x>2\end{array}\right.$，则函数$g\left(x\right)=4f\left(x\right)-{\log }_7\left(\left|x\right|+1\right)$的零点个数为（　　）
