Graphs of Increasing and Decreasing Functions with CONSTANT RATES of change (graph segments are straight lines)
Graphs of Increasing and Decreasing Functions with CONSTANT RATES of change (graph segments are straight lines)
• INCREASING: A function is increasing, if as x increases, y also increases . The graph (reading from left to right) goes up-hill, which means it has a positive slope.
• DECREASING: A function is decreasing, if as x increases, y decreases. The graph goes down-hill, which means it has a negative slope.
• CONSTANT: A function is constant, if as x increases, y stays the same. The graph is a horizontal line with a slope of zero.
