从学校商店商品热销情况看函数的应用

See the application of function from the hot sale of school store goods

数学应用在生活中的每个角落,而函数作为数学的核心之一,在生活中也存在着十分广泛的应用。函数不仅可以表达出两个变量之间的关系,也可以反映出因变量随着自变量变化的趋势。对于一些抽象的、复杂的问题,可以列出函数关系式或者画出函数图像,使得两者之间的关系一目了然,问题也就迎刃而解。函数可以帮助我们更简便、更快捷的解决问题,所以今天我们就从学校商店商品的热销情况去认识函数,去探究函数的应用。

mathematics is applied in every comer of life,and function,as one of the core of mathematics,is also widely used in life.The function can not only express the relationship between two variables,but also reflect the trend of dependent variable changing with independent variable.For some abstract and complex problems,you can list the functional relations or draw a functional image,so that the relationship between the two is clear,the problem is readily solved.Functions can help us solve prob lems more easily and quickly,so today we will know functions from the hot sales of goods in the school store and explore the application of functions.
