函数y=a^x与y=x^a图像的交点问题推导及应用

The Intersection of the Images of Functions y=a^x and y=x^a Derivation and Application

运用常见的导数知识,结合函数y=lnxx的图象,给出了函数y=ax与y=xa图像的交点问题一般结论,并运用这一结论推导出了函数y=ax与y=logaX图象交点的相关结论.

The paper gives a general conclusion on the intersection of the images of functions and,and also derives another two related conclusions on the intersection of,giving a clearer picture of this field of study.
