Kayla is measuring how long it takes a ball to roll down a hill the Bal has a starting velocity of 2.6 m per secondthe ball rolls down the hill for 5.5 seconds and when it reaches the bottom it has a velocity of 8.0 m per second how far did the ball roll during this time?

i think its c if i'm wrong

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 .
