定义型函数信息迁移题 ,是指给出阅读材料 ,设计一个陌生的数学情景 ,定义一个新函数 ,并给出新函数所满足的条件或具备的性质 ;或者给出已知函数 ,再定义一个新概念(如不动点 ) ,把数学知识与方法迁移到这段材料中的一类题 .这类题 ,需要通过阅读分析材料 ,捕捉相关信息 ,通过 A definition-type function information transfer problem refers to giving reading materials, designing an unfamiliar mathematical scenario, defining a new function, and giving the conditions or properties that the new function satisfies, or giving a known function and defining a new one. New concepts (such as fixed points), to transfer mathematics knowledge and methods to a class of questions in this section of material. Such questions need to be read through analytical materials and capture relevant information through
