Given the following function:

Let's determine which graph correctly represents the given equation by determining its approximate coordinates.
Let's determine at x = -1, 0 and 1.
At x = -1,

Point 1 : (-1, 2/7)
At x = 0,

Point 2: (0, 0)
At x = 1,

Point 3: (1, -2/7)
Among the graph, the one that best represents the equation is:
Therefore, the answer is CHOICE B.
