The inverse of a function f is a function f^ (-1) such that, for all x in the domain of f, f^ (-1) (f (x)) = x. Similarly, for all y in the domain of f^ (-1), f (f^ (-1) (y)) = y. Can you always find the inverse of a function? Not every function has an inverse. A function can only have an inverse if it is one-to-one so that no two elements in ...To find percentiles for sums on the calculator, follow these steps. 2 nd DIStR 3:invNorm k = invNorm (area to the left of k, (n)(mean), (n) (n) (standard deviation)) where: k is the k th percentile; mean is the mean of the original distribution; standard deviation is the standard deviation of the original distribution; sample size = nAnswer (Graphics Calculator) a. This time we go to InvN (Inverse Normal) and the tail is to the left (this is the default on the old calculators). The area is 0.2, the mean is 20 and the standard deviation is 5.
