When light from the sun strikes the surface of the earth, this light is absorbed by the ground. the ground, in turn, emits infrared light—which is actually invisible to human eyes—back into the air. what is the effect of this infrared light being released into the air from the ground? a. it makes the air brighter. b. it warms the air. c. it harms the ozone layer. d. it makes the air appear blue.

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 .
