I would check to see if the problem is maybe the square root of 8/3 * the square root of 2/3. Maybe I am wrong, but I would look at the problem again to be sure it is definitely a sum and not a product. There is a benefit to it being a product.

That's really the square root of 9. Look at the word "square root." What do you see? There are two words: square - which is a shape I am sure you are familiar with. root - which has many meanings. In this case, it is talking about one side of the square. So cut out 9 pieces of...

I was going to answer you, but then I tripped so I couldn't. Just kidding. The square root of 8 is a constant. It does not change as x changes. Therefore the graph would look like a line rather than a square root curve. In order for the function to be a square root function, ...
