Which describes how outer space, air, and glass affect the speed of light?

a.
light travels fastest through glass, it travels somewhat slower though outer space and of these three, it travels the slowest through air.

b.
light travels fastest through outer space, it travels somewhat slower though air, and of these three, it travels the slowest through glass.

c.
light travels fastest through air, it travels somewhat slower though glass and of these three, it travels the slowest through outer space.

d.
light travels fastest through glass, it travels somewhat slower though air and of these three, it travels the slowest through outer space.

The following that describes how outer space, air, and glass affect the speed of light is that light travels fastest through outer space, it travels somewhat slower though air, and of these three, it travels the slowest through glass. The answer is letter B.

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 .
