Why do power plants worry about the resistance of the wires?

( PHYSICAL SCIENCE )

Resistors restrict current flow through a circuit.

(The electrons don't easily get from one side to the other)

High voltage is actually needed for to send power over long distances because if you use high current, a lot of the power is lost to the resistance in the wires.

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 .
