Answer:
Not a function.
Does not pass vertical line test.
B.
Step-by-step explanation:
Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.
We say if it passes then it is a function.
It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.
If a single vertical line that you draw touches more than once, then it isn't a function.
When I say draw, I don't mean you should physically do it, but more so imagine it.
Now this particular relation is not a function because I can find a vertical line that touches more than once. Take the vertical line x=5 for example.
It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.
Based on the equation, y = -750·x + 8500, the estimated value of a
motorcycle that is 5 years old is <u>$4,750</u>.
<h3>How can the given equation help to estimate the value of the motorcycle?</h3>
The regression equation that models the data is; y = -750·x + 8500
Where;
y = The value of the brand of motorcycle in dollars
x = The age of the motorcycle
When the motorcycle is 5 years old, we have;
x = 5
y = -750 × 5 + 8500 = 4750
Based on the equation, the estimated value of a motorcycle that is 5 years old, y =<u> $4,750</u>
