<u>Vertex Form of a Vertical Parabola:</u>
Vertex ->
Axis of Symmetry ->
Vertical Scale Factor ->
- To turn into vertex form, we need to complete the square on the right side
- Therefore, if , then completes the square on the right side
- This becomes
- This means that our function in vertex form is
Therefore, the vertex of the graph is .
Well the first part is 27 but the second part is adding 60 to 21 which is 81. dont forget that!
