The graph of y = -8x^2 is an inverted parabola with vertex at (0, 0).
That of y = -8x^2 - 2 is the same as above, except that the whole graph has been shifted 2 units down (Answer D).
Answer:

Step-by-step explanation:
All you have to di is subtract the exponents.
If we are going to analyze the problem very well, the equation that we will be able to make would be: 2x + 6y = 72
72 is the oz of water conditioner to use in his fish tanks.
small tanks would require 2 oz of conditioner
large tanks would require 6 oz of conditioner
There is only one point which satisfy's the above equation.That is the points of (0, 12) and (36, 0)
