Answer:

c.(0, -√5) and (0, √5)

Step-by-step explanation:

The equation represents an ellipse centered on origin (0,0). First, the formula is rearranged to its cannonical form:

\frac{x^{2}}{4} + \frac{y^{2}}{9} = 1

The foci are located in the lines of the semimajor axes, so, the distance between the center and any of the foci is:

c = \sqrt{9 - 4}

c = \sqrt{5}

The foci are located at (0, -\sqrt{5}) and (0,\sqrt{5}). Hence, the answer is C.

Sever21 [200]
Plug \ in \ x+3 \ into \ f(x) \ to \ get \ g(x)
\\\ g(x) = (x+3)^2-2(x+3)+6
\\\ g(x)= x^2+6x+9 -2x-6+6
\\\ g(x) = x^2+4x+9
\\\ -\frac{b}{2a} --\ \textgreater \  vertex
\\\ \frac {-4}{2}
\\\ x \ coordinate = -2, plug \ it \ back \ into \ g(x)
\\\ (-2)^2+4(-2)+9
\\\ 4-8 + 9
\\\ y \ coordinate = 5
\\\ \boxed{(-2,5)}
