A truck accelerated from a velocity of 20 m/s to velocity of 5 m/s in a period of 5 seconds. Determine the acceleration of the truck with the proper units. A. 2 meters/ second

B. -3 meters/ second

C. 3 meters/ second squared

D. -3 meters/ second squared

0.11 m/s and 0.28 m/s should be correct

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 .

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
