A force F with arrow applied to an object of mass m1 produces an acceleration of 3.40 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.50 m/s2.(a) What is the value of the ratio m1/m2?
(b) If m1 and m2 are combined into one object, find its acceleration under the action of the force F with arrow.
m/s2

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 .
