Graphing Quadratics with intercepts

1) Optional: Watch the instructional video shown below. *Important Note: At 5:50, a student makes an important point. In the graph to the left, the x-intercepts (roots) should be equidistant from the axis of symmetry. If this graph was an accurate representation of a quadratic equation, the negative root would pass through the x-axis at (-2, 0), not (-4, 0) because -2 and -4 are equidistant from their midpoint 1. https://youtu.be/60PoL2fESEc 2) On slide 1, use the move tool to drag and drop the vocabulary identifying the appropriate parts of the parabola. Use the caption tool to explain what you KNOW how to find algebraically and what you still need help calculating. 3) On slides 2-5, use the pen and/or label tools to find the x- and y-intercepts of the given quadratic equation. Use the pen tool to plot the three points and sketch a graph of the parabola.
