Acar is driven east for a dstance of 47 km, then north for 27 km, and then in a direction 30 eest of narth for 28 km. determine (a) the megitude of the ca'sta cars total displacement measured trom its starting direction aplacement from ts starting point and () te agle (hrom ant ofth (b) number 14 click if you would like to show werk for this question

prolly a beacuse the momentuem the car has increases while going down hill

im guessing the west of station 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 .
