x 12Solutionfxx12 is not one to one function so inverse doe

Solution

f(x)=(x-1)² is not one to one function so inverse doesnot exist

function is one to one if f(a)=f(b) =>a=b

(a-1)²=(b-1)²

a-1 =b-1 , a-1=-(b-1)

a=b ,a=2-b

we get a=2-b also, so function is not one-one , so inverse does not exist
