v=6

A parabola is open up if a > 0.
The vertex formula:

(h; k) - the coordinates of the vertex

Therefore h = -5 < 0
Answer: B. y = x² + 10x + 24.
In order to get the answer to this problem you will have to go to the thousands place value and look at the number next to the place value and if the number is greater then 5 then you round up which will give you your answer.





Which means your answer is "692,000."
Hope this helps.
If you're solving for x, you'd move all the terms containing x to the left side of the equation:
d^2y/dx^2+4y/x-12y-cos^2(x)+sin^2(x)=0
If you're solving for y, you'd simplify both sides of the equation, then isolating the variable:
y=xcos(2x)
