If a student tried to lift a 350 N box upwards with a lever that is 75 cm long, how much force would they need to provide given a fulcrum 20 cm away from the box.

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 .

when both swimmers do work at the same rate. not lol what like the idiot
