举一反三
- 查找yuangong表中所有电话号码(列名:telephone)的第一位为8或6,第三位为0的电话号码() A: SELECT telephone FROM yuangong WHERE telephone LIKE’[8,6]%0*’ B: SELECT telephone FROM yuangong WHERE telephone LIKE’(8,6)*0%’ C: SELECT telephone FROM yuangong WHERE telephone LIKE’[86]_0%’ D: SELECT telephone FROM yuangong WHERE telephone LIKE’[86]_0*&rsquo
- 设函数fx=e^x,x<0,fx=a+x,x>=0应当怎样选择数a,使得fx成为在
- 设x=(8>1)+5,x的值为() A: 0 B: 1 C: 6 D: 5
- set1 = {x for x in range(10) if x%2==0} print(set1) 以上代码的运行结果为? A: {0, 2, 4, 6} B: {2, 4, 6, 8} C: {0, 2, 4, 6, 8} D: {4, 6, 8}
- 设f(x)具有性质:[tex=8.571x1.357]8gPeznjMnng12qtkk9Vgczii1Sh4d1qJxc9iHYT5+YI=[/tex]证明:必有f(0)=0,[tex=5.5x1.357]rt5qCY7TXHcsFUQrD44nPA==[/tex](p为任意正整数)
