A distance-time graph shows themotion of two bicycle riders. Each rider's motion is represented on thegraph by a diagonal line sloping upward from left to right. The graphshows that they traveled the same distance. However, the line representing the motion of Rider #1 slopes upward more steeply thanthe line representing the motion of Rider #2. Sketch a graphical model ofthe motions of the riders. Develop an argument on which rider arrived athis or her destination first. How do you know? Use evidence to addvalidity to your argument.

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 .

the answer is 100. i just did this lesson and got a 100% on it. : )
