• Sports objects often follow these paths. Polynomial whose largest exponent is 2. SLO – use graphs of quadratics to gain geometric understanding of the algebra that appears in football, baseball, basketball, etc. Refer to general form
• Symmetry! Vertex. Opens up or down depending on sign of a
• Vertex form with tranformations
• Will the vertex be a max or a min?
• (5,0), (1,0), (0,-10)
• What’s different? Vertex &amp; solving for x-intercepts.
