Function value and range in liberal arts mathematics in college entrance examination?
Function value and range in liberal arts mathematics in college entrance examination: There are special multiple-choice questions or fill-in-the-blank questions for finding function value in college entrance examination, which are usually aimed at piecewise functions, more than exponential functions and logarithmic functions. As long as you pay attention to the segmentation interval, you will generally not make mistakes; Function value domain problems usually integrate maxima, monotonicity, symmetry, parity, etc., which are numerous and complex. It is the focus and difficulty of review. The hot spots and error-prone points of college entrance examination are usually divided into several typical questions, so there will be no mistakes, such as how to find the maximum value, monotonous interval, parity, symmetry axis and so on. In addition, the problem of function value domain is most closely related to the establishment of constants. The problem of constant establishment is finally transformed into seeking the maximum value. Please see: /726608875/infocenter# for the solution of range!
