Step 3: Measure the Speed of the Toy Car on the Lower Track
Calculate the average time it took the car to reach each
checkpoint. Record the average times in Table B of your
Student Guide
The average time to the first quarter checkpoint is
seconds
The average time to the second quarter checkpoint is
seconds
The average time to the third quarter checkpoint is
A seconds
The average time to the finish line is seconds.

i think its c if i'm wrong

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 .
