Graphing Standard Form

Standard Form

A quadratic function in standard form is written .

What point is given to you by the standard form? HEADS UP! When you check your answers for multiple choice questions, the correct answer will be highlighted with a green stripe. Green checkmarks mean you were correct for NOT picking it. Confused me too!

Create a table in your notes with 5 columns titled: function, a, b, c, vertex, y-intercept and x-intercept(s). Record the function, a, b, c, then turn on its graph and record the rest of the information. I did the first one for you.
