Which statement about proportional relationships is false? A proportional relationship must graph as a line. A graph of a propor
tional relationship must pass through (0, 0). Each point (or pair) in a proportional relationship must share the same ratio. Each point (or pair) in a proportional relationship must share the same difference.
so hmmm seemingly the graphs meet at -2 and +2 and 0, let's check
so f(x) = g(x) at those points, so let's take the integral of the top - bottom functions for both intervals, namely f(x) - g(x) from -2 to 0 and g(x) - f(x) from 0 to +2.
