一、高考真题答案解析
1. 数学
2017年高考数学试题难度适中,注重考查学生的逻辑思维能力和运算能力。以下是一些典型题目的答案解析:
例题1: 若函数\(f(x)=ax^2+bx+c\)的图象与x轴有两个不同的交点,且这两个交点的横坐标之和为-2,求a、b、c的值。
答案解析: 设两个交点分别为\((x_1, 0)\)和\((x_2, 0)\),则有\(x_1 + x_2 = -2\)。根据韦达定理,\(x_1x_2 = \frac{c}{a}\)。结合题意,可列出方程组: $\( \begin{cases} x_1 + x_2 = -2 \\ x_1x_2 = \frac{c}{a} \end{cases} \)\( 解得\)a = 1\(,\)b = -2\(,\)c = 0$。
