5.1 (Day 3)Graph Quadratic
Functions in vertex form
Goal: To graph quadratic functions written in vertex form and to write quadratic equations in standard form.
(F.IF.7a)
Previously, we graphed a quadratic that was in standard form. Standard form:
Another useful form of a quadratic function is vertex form:
y = a ( x - h )2 + k
• The graph of y = a(x - h)2 + k is the parabola y = ax2 translated
• horizontally h units • vertically k units
Vertex form of a quadratic equation: f(x) = a(x - h)2 + k:
• Vertex:
• Axis of symmetry:
• Graph opens:
For each quadratic function, give the vertex and axis of symmetry.
1. y = -4(x + 1)2 + 5 Vertex: _________ Axis of Symm: _____
