抽象函数是相对于给出具体解析式的函数来说的,它虽然没有具体的表达式,但是有一定的对应法则,满足一定的性质,这种对应法则及函数的相应的性质是解决问题的关键。抽象函数是高考函数命题的新亮点,也一直是难点,这类试题立意好,背景新,学生均感到束手无策.抽象函数的抽象性赋予它丰富的内涵和多变的思维价值,可以考查类比猜测,合情推理的探究能力和创新精神.下面就抽象函数作一探究,以抛砖引玉.
The abstract function is relative to the function that gives a concrete analytical expression. Although it has no specific expression, it has a certain corresponding rule and satisfies certain properties. The corresponding nature of the corresponding rule and function is to solve the problem. The essential. The abstract function is a new highlight of the college entrance examination function proposition, and it has always been a difficult point. Such examination questions are well-established and the background is new. The students feel helpless. The abstractness of the abstract function gives it rich connotation and variable thinking value, and can be used to examine analogy , Reasonable reasoning ability and spirit of innovation. Here’s an abstract function to explore, in order to initiate.
