Final answer:
Option 4: Irrational. The number -4π is an irrational number, 4 is a whole number, an integer, and a rational number, and π is an irrational number.
Step-by-step explanation:
The types of numbers -4π, 4, and π are different. The number -4π is an irrational number, as it is the product of an integer (-4) and the irrational number π. The number 4 is an example of a whole number, an integer, and a rational number. Whole numbers include zero and all positive integers. Since 4 is not negative, it is a whole number. It is also an integer because integers comprise of all whole numbers and their additive inverses (negatives). Additionally, it is a rational number because it can be expressed as a ratio of two integers. Lastly, the number π is famously known as an irrational number since it cannot be expressed as a precise fraction or decimal without recurring or terminating.
