The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the \(y\)-axis. The shape has been reflected in ...

Now, h = -b/2a. Plug in the values into the formula, and you get: The parabola's axis of symmetry (x = h) is a vertical line passing through the vertex, so as demonstrated above, this is x = 1.

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