What is the mass, in kilograms, of a person whose weight on Earth is 670 N (about 150 pounds)? The measurement for gravity on Earth is 9.8 meters per second squared (m/s2). Enter your answer as a number, rounded to the nearest tenth, with the appropriate unit, like this: 4.2 kg

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.
