what is the inverse of f(x)=2-2x

Answers

Answer 1
In the usual sense, it has no inverse function. Since it is not an injection (f(0)=f(2)=0), an inverse function would have to map 0 both to 0 and 2, and that’s impossible.

However, if you restrict the domain to [1,+oo> (to make it injective), and the codomain to [-1,+oo> (to make it surjective), then it has an inverse function, given by g(y)=1+sqrt(y+1).

For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.

Step-by-step explanation:

The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).
