A tornado traveled east across the United States a distance of 600 meters in 6 minutes. What was the velocity of the tornado? A plane flew north for 1,000 kilometers in 10 hours. What was the plane's speed?

velocity of tornado= 100m/min

speed of plain = 100km/hr

what was the answer?

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 .
