9- dois veículos A e B movem-se no mesmo sentido. O veículo A, tem uma velocidade constante de 16m/s. O veículo B está em movimento uniformemente acelerado com uma aceleração de 2m/s² e a velocidade inicial é zero. No instante t=0,os veículos encontram-se na origem. *Qual é,em metros a distância em que estes veículos se cruzam*? A- 32 B - 64 C - 128 D - 256

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 .
