形如y=logax(a>0且a≠1)的函数叫做对数函数,其中x是自变量.单调性在它性质中占有重要地位,它在解决相关问题中有着重要的应用.
A function of the form y = logax (a> 0 and a ≠ 1) is called a logarithmic function, where x is an independent variable. Monotonicity plays an important role in its properties and has an important application in solving related problems.
