A light-year is defined as the distance the light can cover in one year.
The light travels at speed of
, and one year converted into seconds is
So the distance covered by the light in one year is
And this is the distance that corresponds to one light-year.

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.
