The goal of this activity is for students to observe that the x-intercepts can be found by looking at the equation of a quadratic equation in intercept (factored) form, that the axis of symmetry lies halfway between these two points and that the x-coordinate of the vertex is the same as the axis of symmetry.
After making observations and answering critical thinking questions, students will be able to identify the x-intercepts, the axis of symmetry, the vertex of quadratics in intercept form and will be able to use this information to sketch graphs of quadratics in intercept form.
