If it takes 726 watts of power to move a mass 36 meters in 14 seconds, then what is the magnitude of the object’s mass? A. 12.1 kg
B. 20.2 kg
C. 28.8 kg
D. 282 kg

20.2

Explanation: Divide 726/34 and you get 20.16 round it and you get 20.2

i wanna say it’s between b and d, leaning more towards b.

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 .
