A) Find quadratic functions whose x-intercepts are - 3 and 1 with a = 1; a = 2; a = -2; a = 5 B) How does the value of a aftect the intercepts? C) How does the value of a affect the axis of symmetry? D) How does the value of a affect the vertex? E) Compare the x-coordinate of the vertex with the midpoint of the x-intercepts. What might you conclude?
