A 1.7 m long barbell has a 20 kg weight on its right end and a 35 kg weight on the left end. If you ignore the weight of the bar itself, how far from the left end of the barbell is the center of gravity

i'm only doing this for the points : (

found in the nucleus

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
