Replace x with 2.5 into the expression for f(x) and simplify (you might want to use a calculator for this). Do the same with x=12.

Here's a question: What is the human's age when the unicorn is 1,000 years old? 1,000,000 years old? The limit actually tends to negative infinity...that is, when the unicorn becomes old enough, the human's age is a negative number.
