The information we have about the channel on Mars has mostly come from satellite images and scientific models. However, rovers and landers developed by NASA have made it possible to collect information directly from the surface of Mars. Think about the channel on Mars. What information would you want to collect from the surface of Mars to help you determine whether the channel was formed by flowing lava or flowing water?

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 .
