I am confused on how to call up the function

Question

how do you call up the function...

functions.swift

// Enter your code below
func temperatureInFahrenheit(temperature: Double) -> Double {
return temperature * 9 / 5 + 32

}

You may write the function as it:

func temperatureInFahrenheit(_ temperature: Double) -> Double {

      return temperature * 9 / 5 + 32
}

So you can call the function like:

let tempInFahrenheit = temperatureInFahrenheit(20.0)

if you use "_" in the parameters area, you may use only the value without the parameter name.

You could do something like:

let tempInFahrenheit = temperatureInFahrenheit(temperature: 20.0)
