If f(x) is an even function and (6, 8) is one the points on the graph of f(x), which reason explains why (–6, 8) must also be a point on the graph? Since the function is even, the output of a negative x-value and its opposite is the same. Since the function is even, the output of a negative y-value and its opposite is the same. The graph has rotational symmetry, so the point will be reflected across the y-axis. The graph has rotational symmetry, so the point will be rotated 90 degrees about the origin.

    What is the definition of an even function? It is a function which has the property that for every x, f(x) = f(-x). In other words, f is symmetric about the y-axis.
