Question

The vertex of a parabola is (1,3) and another point on the parabola is (-1,-1). Which point is also on the parabola?

A. (-3,3)
B. (0,3)
C. (3,-1)
D. (1,0)

Answer 1

Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.
