Digital ultrasound is being used more frequently for imaging parts of the body. how does this technology combine mechanical (sound) and electromagnetic (light) waves?
a) images are captured using mechanical waves, which are safer, and data is transmitted using faster electromagnetic waves
b) images are captured and transmitted using mechanical waves, but data is stored using electromagnetic waves.
c) images are captured and transmitted using electromagnetic waves, but data is stored using mechanical waves.

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 .
