CAR A is travelling at 27 meters/second and is following closely behind CARB at a distance of 9 meters. The driver of CAR A has a reaction time of 0.5 seconds (the time it takes between seeing the brake lights of CAR B flash and the driver of CARA
hitting the brake).
How far will his car travel during the reaction time?
Will the driver of CAR A hit the driver of CAR B during the time it takes the driver of CAR A to react?
How do you know? Explain your evidence, reasoning, and any calculations you may have performed.

what are the statements? x

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 .
