The interval is increasing if the value of the function f x increases with an increase in the value of x and it is decreasing if f x decreases with a decrease in x Sal finds the intervals where the function f x x 3x is decreasing by analyzing the intervals where f is positive or negative
Explanation On intervals on which f x is positive 0 f x is increasing f x ex2 f x 2xex2 Because f x is never undefined it could possibly change sign You need to remember these rules If f x 0 for every x on some interval I then f x is increasing on the interval If f x
