学习了二次函数,我们就会经常遇到利用二次函数的性质解决生活中的最大值、最小值或最优化等问题,不少同学面对这类最值问题时会束手无策,特别是在处理有关几何问题的最值问题时,更觉得难以下手.事实上,只要认真阅读题目,弄清问题的实质,构建出二次函数,再运用二次函数的有关性质即可快速准确地求解.现举例说明.一、利用二次函数求实际问题的最值例1某水产品养殖企业为指导该企业某种水产品的养殖和销售,对历年来的市场
Learning the quadratic function, we often encounter the use of the nature of the quadratic function to solve the maximum, minimum or optimization of life and other issues, many students will be at a loss what to do when faced with such a problem, especially in the In fact, as long as you carefully read the topic, find out the essence of the problem, construct a quadratic function, and then use the relevant properties of the quadratic function to quickly and accurately solve the problem. An example of using a quadratic function to find the most practical example of a practical example 1 aquaculture enterprises to guide the aquaculture business and sales of some aquatic products, the market over the years
