Dos cuerpos de 1 kg y 2 kg descansan sobre un plano horizontal y un plano inclinado 30°, respectivamente, unidos por una cuerda que pasa a través de una polea. Halla: a) La tensión de la
cuerda y la aceleración del sistema suponiendo que no hay rozamiento. b) Haz el mismo cálculo
suponiendo que en los dos planos existe un coeficiente de rozamiento cinético μK = 0,34.
Sol: 3,27 N; 3,6 N.

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 .
