Answer: choice C
Step-by-step explanation:
The union of events A and B, denoted ∪ , is the collection of all outcomes that are elements of one or the other of the sets A and B, or of both of them. It corresponds to combining descriptions of the two events using the word “or.”
**keep in mind that we don’t write numbers more than once in these sets(choiceB)
so the answer would be
{3,4,5,6,7,8,9}
The answer is A, D, and E because when you add them up they give you 28.3

If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).
Now if <em>a</em> is a big number, the parabola will become narrower.
So it will stretch vertically and become narrower.
