A plastic rod becomes negatively charged when it is rubbed with a piece of wool. How does the rod become charged? Electrons move from the rod to the wool.
Protons move from the rod to the wool.
Electrons move from the wool to the rod.
Protons move from the wool to the rod.

real, smaller and upside-down.   so the answer should be b.

it has to be b, about 97 percent.

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 .
