If your equation is inthe standard formy=ax2+bx+cy=ax2+bx+c, then the formula for theaxis of symmetryis: x=−b2ax=−b2a Vertex Form If your equation is invertex formy=(x−h)2+ky=(x−h)2+k, then the formula foraxisis ...
that divides this parabolic curve into two equal halves is known as the six of symmetry of a quadratic function. The axis of symmetry always passes through the vertex and focus of the parabolic curve. So the {eq}x {/eq}-coordinate of the vertex is the equation of the axis of...
