How do you find the domain and range of #f(x) = x^3 - 3x + 2#?
Domain simply asks, "Where does the function exist on the x-axis?" So, in this function, because
Similarly, range asks, "Where does the function exist on the y-axis?" When you plug the function into a graph, it becomes evident that it will forever go upward toward infinity and forever downwards toward negative infinity on both axes.
