A student has chosen to study a swinging pendulum . The pendulum would bea. a system b. the surroundings c. a universe d. a force

To find:

What a pendulum is?

Explanation:

A system is a matter defined by the walls of space.

A surrounding is an environment around the system in observation.

A pendulum is a system containing the bob of the pendulum and the string to which the bob is attached.

The rest of the environment around the pendulum is considered as the surrounding.

Final

The pendulum the student has chosen to study is a system.

Thus the correct answer is option a.

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 .
