Restrictions in real life are really important for figuring out the range of a function. Let's break this down:
Physical Limits: Think about throwing a ball. The height of the ball can't be negative. That means the possible values for height are only .
Contextual Factors: If you're looking at how much money you make from selling tickets, you can't sell a fraction of a ticket. That means the number of tickets must be a whole number. So, the domain only includes whole numbers.
Undefined Values: Sometimes, functions just don’t work at certain points, like when you try to divide by zero. This also limits what values can be used in the function.
Understanding these limits helps us see which inputs and outputs make sense in real life!
