Determine the vertex and the equation of the axis of symmetry for the following quadratic functions.


a.

The vertex can be found by either looking at the graph or the function’s equation. The vertex is \((4, 1)\).

The equation of the axis of symmetry is \(x = 4\), since \(p = 4\).

b.


The vertex can be found by either looking at the graph or the function’s equation. The vertex is \((βˆ’3, 2)\).

The equation of the axis of symmetry is \(x = βˆ’3\), since \(p = βˆ’3\).
