Explanation: To find when a function is decreasing, you must first take the derivative, then set it equal to 0, and then find between which zero values the function is negative. Parenthesis (single one) is used if the point is not being included in the interval, whereas a bracket is used when the point is included. To write this interval in interval notation, you must use parentheses and square brackets: to indicate if an endpoint is included or not, use a square bracket to show its included (a,b] and parentheses to show its excluded from the interval [a,b).
