Input Tips:

Use = for equality, ≠ for not equal.
Use pi or click π to insert π.
Use ^ for powers, e.g. x^2.
Use sqrt( ) or √ for square roots.
Fractions: type 1/2, not “½”.

\( \begin{array}{l}\text{Compare with vertex form } y = a(x - h)^2 + k. \\ (x + 4) \text{ means } h = -4, \text{ so the axis of symmetry is } x = -4.\end{array} \)
