- From your everyday experiences, identify several pairs of variables that appear to be related and might be described by a function. Include at least one pair that does not involve time. For example, when a person has diabetes, the amount of insulin injected and the number of carbs consumed are a pair of variables that are related - the number of carbs consumed is the independent variable and the amount of insulin injected is the dependent variable (the amount of insulin injected depends on the number of carbs that will be or have been consumed).arrow_forwardIm trying to figure out this problum can someone help expain it.arrow_forward***PLEASE INCLUDE EXCEL OUTPUT WITH YOUR RESPONSEarrow_forward
