Question

Which of the following equations is of a parabola with a vertex at (3, 0)?

y = (x - 3) ²

y = (x + 3) ²

y = x ² - 3

y = x ² + 3

Answer 1

The equation "y = (x - 3)^2" would have the vertex (3,0).

Given the general vertex form of a quadratic function, y = (x - h)² + k, the coordinate (h,k) represents the vertex. In the function above, the value of "h" would be 3, and the value of "k" would be 0. Therefore containing the vertex (3,0)
