"Range" and "value range" are two concepts that we often encounter in our study. Many students often confuse them, but they are actually two different concepts.
"range" is a set of all function values (that is, every element in the set is the value of this function), while "Range" is only a set of some values that meet a certain condition (that is, all elements in the set may not meet this condition). That is to say, the scope is the scope, but the scope is not necessarily the scope.
Definition domain, corresponding rules and value domain are the three basic "components" of function construction. There is no doubt that the principle of "domain priority" is implemented in mathematics at ordinary times.
The main basis of domain definition:
① The denominator of the score cannot be zero.
(2) The number of even roots is not less than zero.
③ The true value of logarithmic function must be greater than zero.
④ The bases of exponential function and logarithmic function must be greater than zero and not equal to 1.
