Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
3xy + 3y2 = 3y (x + y)
It is the equation of a parabola.
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
It is the Cartesian equation of an ellipse.
(x+y)2
(a + x^2)(b + y^2)
X + y
it is (x-y)(x-y) :)
Only when X or Y = 0 That is because (x + y) squared = x^2 + 2xy + y^2 x^2 + 2xy + y^2 = x^2 + y^2 when x or y = 0
(x + y)(x + y)(x + y)
It is a quadratic expression in the variables x and y.
2
(3x + 3y)(x + y) = 3(x + y)2
4
C2x + C2y = C2(x + y)
Your expression is this... x2 + y2/x
