States that the force times the distance on one side of a lever's fulcrum equals the force times the distance on the other side of the fulcrum, this is the:

Explanation:

It is said to be in equilibrium about the fulcrum . It is the principle of moments.

answer: strength i guess

explanation:

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 .
