Below are the answers to the Graphing Quadratics from Vertex form worksheet.  Please review your work and correct all mistakes.  Come to class prepared to ask questions if you need help identifying the key features of quadratic functions: vertex, axis of symmetry, interval of increase, interval of decrease, extrema, max/min value, domain, range, y-intercept, zeroes (how many and what they are).  Practice converting quadratic equations from standard to vertex form and from vertex to standard form.  Your interactive notebooks should be up to date with your notes to help you review for Thursday's quiz and our unit test Tuesday, February 2nd.
