Functions Other than f(x)
We have already seen that a function does not always have to be called "f(x)." Different letters or words can be used to represent different functions
For instance, we can have three different functions such as f(x) = 3x + 1, g(x) = 5x2 and h(x)=2.
You can even name functirons after what values they calculate such as pay(x) for a pay rate function, temp(x) for a temperature function or height(x) for a height function. This is especially common in the sciences and computer programming.
