1

Understand the problem

Determine which domain corresponds to the function described below:

The function represents the height of a child from birth to first grade.

2

Step-by-step solution

According to logic, a child's height from birth until first grade will always be increasing as the child grows.

Therefore, the domain that suits this function is - always increasing.

3

Final Answer

Always increasing.

Key Points to Remember

Essential concepts to master this topic
  • Growth Pattern: Child height increases continuously from birth to first grade
  • Domain Analysis: Examine behavior over entire interval: birth to age 6-7
  • Verification: Check if height ever decreases during normal child development ✓

Common Mistakes

Avoid these frequent errors
  • Confusing domain with range or not considering real-world context
    Don't focus on specific height values or think height could decrease = wrong interpretation! This ignores biological reality of child growth. Always consider what the function actually represents in the real world.

FAQ

Everything you need to know about this question

What's the difference between domain and range in this problem?

+

The domain is the time period (birth to first grade), while the range would be the actual height values. This question asks about the behavior of the function over its domain.

Could a child's height ever decrease during this period?

+

No! Under normal circumstances, children grow continuously. Height might increase slowly at times, but it doesn't decrease. This is why the function is always increasing.

What does 'always increasing' mean for a function?

+

A function is always increasing when its output values get larger as the input values increase. For height vs. time, as time passes, height gets bigger.

How do I analyze real-world function behavior?

+

Think about the real situation first! Ask yourself: What happens in reality? Then match that behavior to mathematical terms like increasing, decreasing, or constant.

Are there exceptions to this growth pattern?

+

In normal child development, height consistently increases. While growth rates may vary (faster or slower periods), the overall trend is always upward during these early years.
