give 3 examples of functions from everyday life that are described verbally.what can you say about the domain and range of each of your functions?
what about mileage vs gasoline consumption?
Or electric power bill vs elec consumption?
Or gasoline consumption/mile vs speed driven?
does weight vs. eating work too?
Three examples of functions from everyday life described verbally are:
1. Temperature Conversion Function: This function converts temperature values from Celsius to Fahrenheit. For example, if the input is the temperature in Celsius, the function output will be the equivalent temperature in Fahrenheit. The domain of this function would be the set of all possible Celsius temperature values, and the range would be the corresponding set of Fahrenheit temperature values.
2. Distance Travelled Function: This function quantifies the relationship between distance travelled by an object and the time taken to travel that distance. For instance, if the input is the time in hours, the output of this function would be the total distance travelled in kilometers. The domain of this function would represent all possible time values, and the range would encompass all possible distance values.
3. Coffee Brewing Time Function: This function determines the brewing time for a specific blend of coffee to achieve a desired strength. Given the input as the desired strength of the coffee, the output of this function would be the corresponding brewing time in minutes. The domain of this function would consist of all possible desired strengths of the coffee, while the range would include the corresponding brewing times.
Note that the domain and range of each function can vary depending on the specific context and limitations of the situation. It's important to consider any constraints that may arise due to physical limitations or practicality when determining the domain and range of a function in real-life scenarios.
