Force A is the amount of force required to pull a 20 kg box across a carpeted floor. Force B is the amount of force required to pull the same box across ice. Wha
is typically true about the relationship between the two forces?

A. Force A is greater than Force B
B. Force A is less than Force B
C. Force A equals Force B, and both are less than 20 kg
D. Force A equals Force B, and both are equal to 20 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 .

+15-35=-20
