Answer:
Step-by-step explanation:
we know that
The graph of the figure represent a vertical parabola open upward
The vertex represent a minimum
The vertex of the quadratic equation is the point (h,k)
The range of the quadratic equation is the interval for y [k,∞)
Looking at the graph
The vertex is the point (0,-6)
therefore
The range is the interval [-6,∞)
Answer:
I'm pretty sure the answer is C
The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1
a=10/2=5
b=8/2=4
put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1
Simplify and the answer is (x^2/16)+(y^2/25)=1
