Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the derivative property?The derivative of a constant function is identically zero
2. What is the polynomial degree?A non-zero constant function is a polynomial of degree 0
3. How does a constant function look on a graph?It is drawn as a horizontal line that stays at the same height y=c while the x‑axis moves left and right.
4. Why is the derivative of a constant function zero?Because the function never changes, its rate of change is zero everywhere, so the derivative is 0.

Domain: The set of all possible input values for a function.
Codomain: The set of all possible output values for a function.
Rate of Change: How quickly a value is increasing or decreasing over time or another variable.
Category Theory: A branch of mathematics that studies abstract structures and their relationships.
