函數(shù)在高中數(shù)學(xué)中占有很重要的比重，因而作為函數(shù)的第一節(jié)內(nèi)容，主要從三個實例出發(fā)，引出函數(shù)的概念.從而就函數(shù)概念的分析判斷函數(shù)，求定義域和函數(shù)值，再結(jié)合三要素判斷函數(shù)相等.課程目標1.理解函數(shù)的定義、函數(shù)的定義域、值域及對應(yīng)法則。2.掌握判定函數(shù)和函數(shù)相等的方法。3.學(xué)會求函數(shù)的定義域與函數(shù)值。數(shù)學(xué)學(xué)科素養(yǎng)1.數(shù)學(xué)抽象：通過教材中四個實例總結(jié)函數(shù)定義；2.邏輯推理：相等函數(shù)的判斷；3.數(shù)學(xué)運算：求函數(shù)定義域和求函數(shù)值；4.數(shù)據(jù)分析：運用分離常數(shù)法和換元法求值域；5.數(shù)學(xué)建模：通過從實際問題中抽象概括出函數(shù)概念的活動，培養(yǎng)學(xué)生從“特殊到一般”的分析問題的能力，提高學(xué)生的抽象概括能力。重點：函數(shù)的概念，函數(shù)的三要素。難點：函數(shù)概念及符號y=f(x)的理解。
