Increasing And Decreasing Functions Examples Solutions Worksheets Review how to work with increasing and decreasing functions in this precalculus tutorial. watch and learn now! then take an online precalculus course at st. The function would be positive, but the function would be decreasing until it hits its vertex or minimum point if the parabola is upward facing. if the function is decreasing, it has a negative rate of growth. in other words, while the function is decreasing, its slope would be negative. you could name an interval where the function is positive. Constant functions. a constant function is a horizontal line: lines. in fact lines are either increasing, decreasing, or constant. the equation of a line is: y = mx b. the slope m tells us if the function is increasing, decreasing or constant:. Increasing and decreasing functions examples. example 1: determine the interval (s) on which f (x) = xe x is increasing using the rules of increasing and decreasing functions. solution: to determine the interval where f (x) is increasing, let us find the derivative of f (x). f (x) = xe x.
