Move +3 to the right side of the equal sign (which becomes -3) in order to combine the numbers to find x:

x=-9-3

-9-3 is -12

x=-12

x + 3 = -9    <em>subtract 3 from both sides</em>

x + 3 - 3 = -9 - 3

<h3>x = -12</h3>

Which of the equations below could be the equation of this parabola?
Mademuasel [1]

Answer:

Option B: y = -\frac{1}{2} x^2

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

y = ax^2 + bx + c

With a negative value of 'a'

The vertex is (0,0), so we have that:

0 = 0a + 0b + c

c = 0

The x-coordinate of the vertex is given by the equation:

x\_vertex = -b/2a

-b/2a = 0

b = 0

So we have a function in the model:

y = ax^2

With a < 0

The only option with this format is B:

y = -\frac{1}{2} x^2
