An electric motor is used in the compressor of a refrigerator. the motor is responsible for circulate the coolant liquid through two sets of coils: the compressor and the evaporator. in this case, the motor is
a. using the magnetic field to cool the refrigerator.
b. converting mechanical energy into electrical energy.
c. using a magnetic field to create electrical energy.
d. converting electrical energy into mechanical energy.

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 .
