Answer Details
The function of money that is mostly affected by inflation is the "store of value."
Inflation is when the overall prices of goods and services in an economy rise over time. This means that the value of money decreases over time as it can buy less and less. For example, if you have $100 today and there is an inflation rate of 2%, then next year your $100 will only be able to buy what $98 can buy today.
So, the "store of value" function of money is affected because money is not retaining its value as well as it used to, making it a less effective way to save and hold onto wealth.
However, the other functions of money - "medium of exchange," "measure of value," and "unit of account" - are less affected by inflation. These functions involve using money as a way to buy goods and services, measure the value of goods and services, and keep track of financial transactions, respectively, and can still be effectively carried out even with some inflation.
