含参数的零点问题既有一定的难度,又是近几年高考的常见题型。其实,这类问题还是有规律可循的。只要我们能够探寻到这个规律,就能找出行之有效的解决方案,让含参零点问题不再神秘,让学生有法可施。零点问题是高考数学江苏卷函数内容考查的热点问题,近年来以指数函数、对数函数为载体的含参零点问题几乎每年都有,常作为压轴题出现,具有很好的区分作用。 Zero parameters with both the difficulty of a certain degree, but also common entrance examination in recent years, the type of question. In fact, this kind of problem still follows the law. As long as we can find out the law, we can find effective solutions to make the issue of reference points zero no longer mysterious and give students a chance. The problem of zero is a hot issue in examining the contents of the math curriculums in the college entrance examination. In recent years, the problem of parametric zero with parametric functions and logarithmic functions has been carried out almost every year, often as a finale, which has a very good distinguishing effect.
