I was diagnosed with acid reflux a few months ago. I'm on Prilosec now (20 mg. a day) and was on Protonix for 3 weeks before that. When I started the Protonix, I noticed that my stool color changed to a yellow color and that there was yellow seepage also (almost like the color of yellow mustard). Sorry to be so graphic here, but it concerns me a little. The stool consistency is the same, which is basically normal for me.
Finding the Range of a Function of a Relation. 1  1. Write down the relation. A relation is a set of ordered pairs with of x and y coordinates. 2  2. List the y-coordinates of the relation. To find the range of the relation, simply write down all of the y-coordinates of each ordered pair: {-3, 6, -1, 6, 3}.
We will deal with functions for which both domain and the range are the set (or subset) of real numbers A function can be defined by: (i) Set of ordered pairs Example: {(1,a), (2,b), (3,c), (4,a)} is a function, since there are no two pairs with the same first component. The domain is then the set {1,2,3,4} and the range is the set {a,b,c} Example: {(1,a), (2,b), (1,c), (4,a)} is not a function, since there are two pairs with the first component 1
