Using a streak test on a mineral that is harder than 7 on Mohs scale would not be very useful True or False Fracture is the way minerals break along smooth planes of weakness. True or False

Cleavage is the way minerals break with uneven, jagged or rough surfaces True or False

The way light reflects off a mineral is called transparency. True or False

Minerals are the building blocks of rocks. True or False

Mohs scale measures a mineral’s streak. True or False

Color is the most reliable test for identifying a mineral. True or False

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 .
