2006-2007学年高一数学集合与函数测试题(国外英语资料) This document is collected by individuals, for exchange learning only. If there is any mistake, please correct me! High school math set and function test for the 2006-2007 academic year Name class score (examination time 120 minutes, out of 150 points form: closed volume) A choice: (the title of 10 items, each item of 5 points, a total of 50 points, the four options for each question there are, only one is in line with the requirements of the subject.) 1, here are four propositions: the original proposition is true, it is not necessarily the converse is true; the original proposition is true, its not certain whether the proposition is true; the original proposition is true, its inverse proposition must be true; the proposition whether a proposition is true, then it is really a converse proposition. The correct one is () A, B, II. C, D, II 2 A, B=A, B, C=C, A, the relationship between C (have) A, A, B, C, C, A = C, D are all wrong 3, if AB, CB, then A is C A sufficient and unnecessary conditions B necessary and not sufficient C sufficient and necessary condition D is neither sufficient nor necessary 4. Make sure that the mapping of function y=x2+1 is () Mapping from A R to R mapping from B R+ to R+ C R to R+ mapping, D, R to [1, + + mapping 5, A={x, 2 x 3, B={x, x+1, 2}, A, B= , () A (-2, 1) B (-3, 3) C (1,3) D (- 2, 3), (2 +, -) 6, proposition xy=0x=0 or y=0s negative proposition is () A xy = 0 x = 0 or y = 0 B xy = 0 x = 0 and y = 0 C x = 0 or y = 0 xy = 0 D x = 0 and y = 0, xy = 0 7, function y=1- () A is monotonically increasing in (-1 + +), and B is monotonically decreasing in (-1 + +) C is monotonically decreasing in (1 + +), and D is monotonically increasing in (1 + +) In 8, x+y=0, x2+y2 0 and XY 0 and xy = 0. X2+y2=0, which is x, y is not necessary but not sufficient condition for a 0 (a). A 4, B 3, C 2, D 1 9, the known function f (x) =4x2-mx+5 is an increase function on the interval, then the range of M is () A (-,, -16)
