The standard normal probability function is used to describe many different populations. Its graph is the well-known normal curve. This function is defined below. Give the intervals where the functions is increasing and decreasing -2.n f(x)=- Come Determine the interval(s) on which the function is increasing Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The function is increasing on the interval(s) (Type your answer in interval notation. Simplify your answer. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed) B. The function is never increasing
