Entirely possible, yes.
If you mean y =9x^2 -4 , than the range is the possible y values. Range = 0<= y < infinity.
2
Domain: All Possible "x" values Range: All possible "y" values
I would clean that up a little bit to make it look like, y^2+4y-4. which will factor out into, (y+2)*(y-2) So the two possible answers is -2 and 2
That will depend entirely on the equation which has not been given.
That is irrelevant, there is not possible way y=xy, and there is no possible way xy=x.
The 3 possible answers are Quadrant 3 and Quadrant 4 and y-axis
Not entirely sure what standard form is, but... probably y = x + 5
Possible, but unlikely.
It is not possible to answer the question without the numerical value of Y.
That depends entirely on the value of x.
y's is possible
Yes, it is a straight line
Domain is what you can plug into the function (possible x values for y=f(x) type functions) and range is the possible values you can get out (possible y values).
That of course will depend entirely on the straight line equation which has not been given but in general in the equation y = mx+b the slope is m and b is the y intercept
The range of y=2x is All Real Numbers
It is quite possible, depending on X, a and y.
