A race car starts from a rest to increases its speed to 23 m/s over a distance of 120 m. Calculate acceleration.

Acceleration=115m/s²

Explanation:

speed=distance/time

23=120/time

/120 on both sides

0.2s is time

acceleration= change in velocity/time taken

23/0.2=115

acceleration=115m/s²

neither accurate nor precise.

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 .
