D
分析:根據(jù)導(dǎo)函數(shù)的圖象和函數(shù)單調(diào)性之間的關(guān)系,如導(dǎo)函數(shù)的圖象在x軸上方,則原函數(shù)在該區(qū)間上是增函數(shù),如導(dǎo)函數(shù)的圖象在x軸下方,則原函數(shù)在該區(qū)間上是減函數(shù),由y=f′(x)的圖象得函數(shù)y=f(x)的圖象.
解答:由導(dǎo)函數(shù)f′(x)的圖象可知,
f′(x)在x∈(0,1)上恒大于零,在x∈(-1,0)上恒小于0,
由函數(shù)的導(dǎo)數(shù)與函數(shù)的單調(diào)性關(guān)系可以知道,
函數(shù)f(x)在x∈(0,1)上單調(diào)遞增,在x∈(-1,0)上單調(diào)遞減,結(jié)合選項可知選D.
故選D.
點評:考查導(dǎo)數(shù)和函數(shù)單調(diào)性之間的關(guān)系,導(dǎo)數(shù)f′(x)≥0,函數(shù)f(x)在該區(qū)間上是增函數(shù);導(dǎo)數(shù)f′(x)≤0,函數(shù)f(x)在該區(qū)間上是減函數(shù),以及識圖能力,體現(xiàn)了數(shù)形結(jié)合的思想,屬基礎(chǔ)題.
