(x-2)(y 2x-4)= x-2 ^3 y=x a 345631-(x-2)(y+2x-4)= x-2 ^3 y=x+a

WebAs you have pointed out Putting ( x, y) = ( t, t 2) will give you lim t → 0 2 t 4 2 t 4 = lim t → 0 1 = 1 Using the path ( x, y) = ( t, 0) gives lim t → 0 2 t 2 ⋅ 0 t 4 = lim t → 0 0 = 0 Since you got

(x-2)(y+2x-4)= x-2 ^3 y=x+a-Web反函数的定义是把原函数的x当做反函数的y，把原函数的y当作反函数的x 所以根据这个就很容易求出该函数的反函数即x=2^y/ (2^y1),由于这个可能比较难算，可把2^y当作一个整体再经过计Weby^2 = x^32x^2 Natural Language;
