Using First Differences to Determine if a Table Represents a Linear Function
• 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.
