A race car travels in a straight line from the starting line to the finish line in 12.0 seconds. The race car accelerated from a stopped position to 90 m/s b the time it reached the finish line. What was the acceleration of the race car?

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 .

can somebody give me the answer so i can graduate
