Find the equation of the line of symmetry and the coordinates of the ... x + 1)(x – 3)\) and so the graph will cross the \(x\)-axis at \(x = -1\) and \(x = 3\). The constant term in the equation ...

(If a were zero, you would have a linear equation.) Through this equation, you can identify the vertex, axis of symmetry and the direction in which the parabola opens. Follow these steps to draw a ...
