Once students know the relationship between a quadratic trinomial expression and its factors, they can gain a conceptual understanding of how those factors relate to the zeros of the parabola the expression graphs. I designed this activity to guide students in discovering the relationship between the factors and the zeros of a parabola, and to write their own rule in determining how to identify the zeros of a parabola when given only factors. The level of inquiry and guidance in this activity i

Graphing Quadratics from Vertex, Zeros, and Y-Int This worksheet has students graph parabolas from given information. They must color-code the features of each graph to identify whether it is a vertex, zero, or y-intercept. Some graphs will not have zeros. A CHALLENGE section is included at the end for students to match four quadratic expressions with the graphs they produce. This section involves no directions on how to identify the correct graphs so students must think back to what they
