Answer: {y∈R: y≤6} or [6,∞)
Explanation:
This problem doesn't require too much math. If you look at the equation given, you can see that it is a quadratic equation in the form of
. Since this is a quadratic equation, we have an idea of that the graph would look like. It either curves up or down. Since this is a positive equation, 
, we know that this is going to curve up. In order to find the minimum of the curve, you would use 
.
This means the x value of the parabola is -2. To find the y, you plug -2 into the original equation.
Now that we know the y value of the minimum/vertex is 6, and it is determined that the parabola curves up, the range is y≤6 because the range starts at 6 and goes off toward infinity.

Answer:
The pyramid starts with producers, which have the most energy, then primary consumers eat the plants. Then secondary consumers eat the primary consumers. Top level consumers eat the secondary consumers, then decomposers start the process over again. As the pyramid gets higher, there is less energy between levels.
