What additional information is obtained from measurements on an ordinal scale compared to measurements on a nominal scale? comparison of the magnitudes of two measurements (such as one being twice as large as the other) direction of difference (greater or less) between two measurements magnitude of difference between two measurements

truck y has a greater velocity than truck x.

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 .
