四、简答题答案：

1.函数\(f(x)=\frac{1}{x}\)的性质：

-定义域：\((-\infty,0)\cup(0,+\infty)\)

-值域：\((-\infty,0)\cup(0,+\infty)\)

-奇偶性：奇函数

-单调性：在\((-\infty,0)\)和\((0,+\infty)\)上均单调递减

2.等差数列的通项公式：

-通项公式\(a_n=a_1+(n-1)d\)

-代入已知条件\(a_1=1\)，\(a_2=3\)，\(a_3=5\)，得\(d=2\)

-通项公式为\(a_n=2+2(n-1)=2n\)

-证明：\(a_n=2+2(n-1)\)，\(a_{n+1}=2+2(n)\)，\(a_{n+1}-a_n=2\)，所以\(\{a_n\}\)是等差数列

3.等比数列的\(abc\)值：

-\(f'(x)=2x-4\)，令\(f'(x)=0\)，解得\(x=2\)

-\(f''(x)=2\)，\(f''(2)=2>0\)，所以\(x=2\)是极小值点

-极小值为\(f(2)=2^2-4\cdot2+3=-1\)

3.等比数列的前10项和：

-通项公式\(a_n=2\cdot3^{n-1}\)

-前10项和\(S_{10}=\frac{2(1-3^{10})}{1-3}=59049\)
