<span>Pre-Calculus - Identify where a function is increasing decreasing or constant from the graph </span> Example: The graph<span> shown above is decreasing from the point (3,4) to the point (5,-5), described as decreasing when 3 < x < 5. Using interval notation, it is described as decreasing on the interval (3,5). </span>Constant<span>: A function is </span>constant<span>, if as x increases (reading from left to right), y stays the same.
