有下列四點:M(1,2),N(3,),P(1,-1),Q(-2,-4),其中在函數的圖象上的是

A.M點

B.N點

C.P點

D.Q點

試題答案

B

試題解析

把M(1,2),N(3,),P(1,-1),Q(-2,-4)的橫坐標代入解析式求解,如果得到的解等于縱坐標,則在函數圖象上,否則不在圖象上.

解答:M(1,2),y==1,2≠1,所以不在函數圖象上;

N(3,),y==,在函數圖象上;

P(1,-1),y==1,-1≠1,所以不在函數圖象上;

Q(-2,-4),y==4,4≠-4,所以不在函數圖象上.

故選B.

點評:本題主要考查點在函數圖象上的含義,點在函數圖象上,則點的坐標滿足函數解析式.
