WebA function relates an input to an output. Saying " f (4) = 16 " is like saying 4 is somehow related to 16. Or 4 → 16. Example: this tree grows 20 cm every year, so the height of the tree is related to its age using the function h: h(age) = age × 20. So, if the age is 10 years, the height is: h(10) = 10 × 20 = 200 cm. WebOct 20, 2024 · The BMW internal model code F30 refers to the sixth-generation 3 Series sedan, produced between 2011 and 2024.
