    General formula x^2 + y^2 = radius^2 is a circle So it is a circle however, a circle is a special kind of ellipse.. so I would say both a circle and an ellipse

    Are those 2's outside the parentheses indented to be exponents? If not, this is not any of those, it's a line. If so then it's a circle and an elipse

    If the equation of a parabola is y = 7(x - 4)2 + v, and its vertex is (4, -2), what is the value of v in the equation?

    Recall that the general form for a parabola is: \[y-y_0 = K(x-x_0)^2\] Where K is a multiplicative constant that changes the scale of the parabola, and \(x_0, y_0 \) are the coordinates of the vertex.

    in your case, moving the v to the otherside shows that \(y_0 = v\). So v would be the y value of your vertex.
