"Spiderman is swinging from skyscrapers. He swings north 11 km, chasing down the Green Goblin. He then swings south 7 km to get a hot dog. After that, he swings 15 km to go to school. Finally, at the end of the day, he swings back home south 6.5 km to his apartment. He did this all in 8 hours A. What is Spiderman's average velocity?
B. What is Spiderman's average speed?

Please at least give me help with how to calculate this. Don't waste your time doing the actual problem. I just need the method of solving it.

Explanation:

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 .
