Two intuitive error can not be ignored
): +2 X + n,[link widoczny dla zalogowanych], 1) problem in the function domain of R,[link widoczny dla zalogowanych], f ()> 0 constant established equivalent to the function f (x) constant on the axis side images,[link widoczny dla zalogowanych], so △ <0; and 2) the range of functions in question for the R, need to f () can take over all real numbers greater than 0, so the function f () the image must be a point of intersection with the axis, so △ ≥ 0. This knowledge, the function y = lg (x +2 x + population) in the domain and range can not simultaneously R. Question Group 61) the function y = +2 x + mouth on a real number, range is 【0, + oo), find n values. 2) The function Y = +2 x + port number of a real z, the function values are non-negative, find the range of n. Solution 1) was intended by the title, △ ... 44a0. Port = 1.2) for each question that was 4-4 mouth △ ≤ 0 ≤ 0,. '. Population ≥ 1. Commentary 1) The range of functions in question is 【0, + oo), Y can be taken to refer to all non-negative real number, and 2), the only non-negative values of y can be.
