The two graphs have opposite slope. For f(x), m = 2, which means that the rise is 2 and run is 1. This means for every 2 units the graph goes up, it goes 1 unit to the right.. For g(x) however, m = -2, which means that the rise is -2 and run is 1. This means that for every 2 units the graph goes up, it goes 1 unit to the right. Graphing the two graphs shows that the two graphs are really reflections of each other in the y-axis.

The domain of both functions is: x element R, because both of them exist for every x-value. The range also for both is y element R, because graphing them shows that if the graphs were to infinitely continue, they would always taken on every y-value on both the positive and negative sides.
