25 because 5 (the number of sticks) times 5 (the number of houses) equals 25
The function is odd just substitute f(x) for f(-x) and replace all the x's with -x's then go back to the original problem and substitute f(x) for -f(x) and multiply the original problem by -1 and since f(-x) and -f(x) are equal, it is odd. if the original problem, f(x) and f(-x) were equal it would be even and if none of the three are equal it would be neither. the answer to this question is odd because f(-x) and -f(x) are equal.
Answer:
14 is a positive integer, then it belongs to the set of natural numbers.
1 and 5/9 are rational numbers. The second is already a fraction and the first one, 1, is a natural number, but all the natural numbers can be written as the result of a fraction. For example: 1=6/6.
About the last number, I don't know if it's written correctly. That should be pi maybe, that is 3.14159.... In that case it's an irrational number.
Irrational numbers are all those real numbers that are not rational.
In general you have that:
ℕ ⊂ ℤ ⊂ ℚ ⊂ ℝ
ℕ. Natural numbers. It's the "smallest" one.
ℤ. Integers. Made with positive and negative natural numbers. Includes the natural numbers then.
ℚ. Rational numbers. Everything that can be written as a fraction. Includes both ℕ and ℤ.
ℝ. Real numbers. Any kind of number, fraction or not.
