The answer is C.
It’s a solid line so you know it has to be an inequality with a “or equal to” sign. Which leaves you with B or C. Find a point that isn’t on the line to test, use origin to make it simple. Plug it in for the x and y values. So 0 is greater than it equal to 0 - 3 which is -3. 0 is greater than -3 which means C is correct.

Step-by-step explanation:
I think the first part of that is asking for the equation for the line of symmetry, although I do not have access to your drop down menu to know for sure! The axis of symmetry is the equation that splits the parabola into 2 parts that are mirror images of each other. In this type of parabola, it will be an "x = " equation. The line that splits the parabola in half is the line x = -2. The function is increasing where the y values are going up. This happens in the interval (-∞, -2].
The function is decreasing where the y values are going down. This happens in the interval [-2, ∞)

A quick way to do this sort of question:
First add the last number and the first number:
1 + 960 = 961
Then divide the total amount of numbers by 2.
960 ÷2 = 480
Now multiply these two numbers together:
961 × 480 = 461280
Answer:
The number is 10
Step-by-step explanation:
Let x be the number
product is multiply
12 + (2x) = 4x -8
Subtract 2x from each side
12+2x-2x = 4x-2x-8
12 = 2x-8
Add 8 to each side
12+8 = 2x-8+8
20 = 2x
Divide by 2
20/2 = 2x/2
10 =x
