Answer:
Step-by-step explanation:
Find the horizontal distance of 230 and find the Vertical distance , which is where the black dot is located.
The black dot is on 49 inches.

One thing everyone always forgets is we don't usually see the <em>entire</em> graph. Once out of the frame, these functions can do anything they want.
From what we can see, only the bottom right one is always decreasing.
Answer: bottom right
By the way, the top right graph (a vertical line) isn't a function.
The vertex is when x=0, so (0, 2) is the answer.
