Concepts:
When the curve or line of a function rises, the function is described as increasing. The slope of an increasing function is positive.
When the curve or line of a function rises, the function is described as increasing.
The slope of an increasing function is positive.
When the curve or line of a function falls, the function is described as decreasing. The slope of a decreasing function is negative.
When the curve or line of a function falls, the function is described as decreasing.
The slope of a decreasing function is negative.
When the line of a function is horizontal, the function is described as constant. The slope of a constant function is 0.
When the line of a function is horizontal, the function is described as constant.
