السلام عليكم.

the function,f and g,given by : f(x)=x^2-4x+4,and g(x)=2sin(x).;l
a)find the domian of the functionh(x)=g(x)\f(x),l
b)show that f is not one-one,and determine(the largest) sub-domians on which f is one-one.find the inverse of f on a sub-domian containing,the value, x=2
c)find the function g(f(x)) and specify the range and the domian of this function.

شكرا جميعا لو سمحتوا افيدوني قريبا.
