Storyboard Text

  • Can you help me find the vertex of a parabola for this function?
  • Sure, you want me to tell you the definition of it?
  • Yea, and then I will know how to plot it.
  • You must find the axis of symmetry, then substitute for x to find the y coordinate of the vertex, get it?
  • Yea, that makes more sense than how the teacher explained it. Now I just need to plot the vertex on a graph, right?
  • Yea, good job!
