Calculate the change in time for each quarter of the track. record the change in time in table e of your student guide. the change in time for the first quarter is seconds. the change in time for the second quarter is seconds. the change in time for the third quarter is seconds. the change in time for the fourth quarter is seconds.

The three pictures you attached represent three different runs of the toy car.

Here's the data for the first run:

The change in time for the first quarter is 1.38 seconds.

The change in time for the second quarter is (2.19-1.38) = 0.81 seconds.

The change in time for the third quarter is (2.80 - 2.19) =  0.61 seconds.

The change in time for the fourth quarter is (3.31 - 2.80) = 0.51 seconds.

The quarters are all the same length, but the times are getting shorter.

The car must be getting faster !  

Maybe gravity is pulling it down, do ya reckon ?

6/12=1/2

step-by-step explanation:

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 .
