a the car is at rest at a traffic light when the light turns Green the car takes off accelerating an uniformly for 30 seconds to a velocity of 15 Ms to the negative 1 at the same time that the car takes off a truck buses is traveling at a constant velocity of 10 Ms negative and the following graphs represent the motion of both vehicles

magnityde and direction

f=ma newton

f=100x2.5=250n

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 .
