<h3>
Answer: Choice A. Graph (1)</h3>
Reasoning:
If it is at all possible to draw a single vertical line through more than one point on the curve, then the graph is not a function. With graphs (2), (3) and (4), we can draw a vertical line through more than one point on those curves, so they aren't functions. Graph (1) is the only thing left. This graph is a function because it is not possible to draw a single vertical line through more than one point. It passes the vertical line test. Any input (x) leads to exactly one and only one y output.
Nice work on getting the correct answer when you chose "graph (1)".

The answer is B. The next crayon Laura picks is NOT red.
So 5 liters of natural for every 7 synthetic, so 5 / 12 liters are natural oil.
so; 684 × (5/12) = 285 liters of natural oil
Hope this helps!
