Question
Could you please check my answers and help me with one of them?
Find the inverse of the one to one function
1. f(x)-4x+7
-I got f^-1(x)=x-7/(-4)
2. f(x)= square root of x-8
-I got f^-1(x)=x^2-8
3. f(x)=4/(5x-1)
This one I don't understand how to find the inverse of the one to one function.

Why is the square of an addiction : (a+b)^2 = a^2+b^2 +2ab? Write an example describing the operation.
