一、选择题（每小题
4分，共32分）（1）若函数
<Object: word/embeddings/oleObject1.bin>
在<Object: word/embeddings/oleObject2.bin>
处连续，则（　）。
A.<Object: word/embeddings/oleObject3.bin>
B.<Object: word/embeddings/oleObject4.bin>
C.<Object: word/embeddings/oleObject5.bin>
D.<Object: word/embeddings/oleObject6.bin>
【答案】
A【解析】
由连续的定义可知：
<Object: word/embeddings/oleObject7.bin>
其中<Object: word/embeddings/oleObject8.bin>
，<Object: word/embeddings/oleObject9.bin>
，从而<Object: word/embeddings/oleObject10.bin>
，也即<Object: word/e ...
