Question

Each year, Britney goes in for an annual physical. As part of the physical, the doctor measures Britney's height. The function f(x) gives Britney's height in feet when she is x years old.
What does f(5)>f(4) tell you?

Answer 1

The notation \( f(5) > f(4) \) indicates that Britney's height at age 5 is greater than her height at age 4. This tells you that between the ages of 4 and 5, Britney has grown taller. In other words, it reflects a positive change in her height during that one-year period, indicating that she is still growing as a child.
