23.3.6 Reading the Graph from the Coefficients

Core idea

a tells you which way it opens, c tells you where it crosses the y-axis, and b together with a tells you which side the axis falls on.

Module goal. Move from vertex form to the general form, and master how to find the three geometric essentials along with the graph's properties.
