1) The domain is all the possible x values in the function so it would be [-4,4]
2) There are only 3 zeros shown on the graph and they are (-2, 0) (0, 0) (2, 0) the zeros are the value of x when y = 0.
3)The function is positive/Negative is asking for what x values make the y values positive aka interval notation. The function is positive if x = (0, 2) because 0 and 2 aren't included you use parentheses () instead of brackets []
The function is negative if x [-4, -2), (-2,0), (2,4]
The "plus x minus two x" part basically means "minus x".
So, "six minux x equals five".
This means that six minus five is x. So, x is one!
Now, let's check this in the problem: replace x with 1. Six plus one minus two ones equals five? Yes, it does!
The answer is x=1.
