What are the coordinates of the point (x,y)?
Give the equation for the path of the ball, showing all work. Explain why you do each step.
Include a screenshot of the graph of your equation (use Desmos.com), verifying that it goes through the given points. May attach to end of the document.
Problem 10:
The total time T (in hours) of the trip as a function of the distance x (in miles). Make sure you show all your work to come up with this equation, and explain each step and what it represents.
The domain of the function. Explain why this domain makes sense, and show work as needed.
Graph the function using the graphing utility on Desmos.com. Take a screenshot: The graph should be focused over the domain of the function. May attach to end of document
Find the value of x that minimizes T. Desmos.com will note this ordered pair for you automatically. If it does not, then you can click various points of the graph and it will display the ordered pair.
What does the ordered pair of the minimum for T represent in our situation and what does the value of T tell us? Write a brief paragraph interpreting these values.
CAN I GET THE GRAPHS FROM DEMOS AND TYPE THE ANSWERS SO THAT I CAN READ IT. THANKS

1) the path of the ball follows an absolute value equation
with vertex at
( x , y ) = ( 12/2 , 8 )
hence , vertex is ( 6 , 8)
standard absolute value equation is written as
y = a | x- h | + k
plugging the values of the vertex
y = - | x - 6 | + 8
graph of equation shown below
