Remark
There is nothing like a graph to settle arguments about which property is to be checked.
Property One
The graph's domain is (-∞<x<∞) there are no restrictions. So property 1 is false.
Property two
The graph says that property two is true. You could complete the square to confirm it. When you do you get
y = -(x^2 + 4x) + 2
y = -(x^2 + 4x + 4) + 2 + 4
y = -(x + 2)^2 + 6 So the y value must be less that 6 ( or equal to 6)
Property Three
Property 3 is true if you are referring to the domain and neither -2 nor - infinity are included.
Property Four
Property Four is not true, It begins to decrease when x>-2 to + infinity
Property Five
It is positive (2).

Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.
The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.
Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.
For example:-
1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, is an irrational number but none of the rest.

Answer:
16 bags
Step-by-step explanation:
To find this, we <em>divide 2 over 1/8</em>, to see how many <em>units of 1/8 fits into that of 2</em>.
can be rewritten as <em>2*8</em>. 2*8 = 16 bags.
