At Coaster World, the tallest rollercoaster is The Pinnacle. The top of the first hill is 40 meters high. It takes 160 Newtons of force to bring a car to the top of the first hill. It takes 10 seconds to get to the top of the hill. How much work is done? How fast are you travelling, on average, to the top of the first hill? calculate all of these( important) :

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 .

b. false

explanation:

suppose a rock in free fall is dropped off a cliff. after falling for 5 seconds, its speed would not be 100 m/s.
