Take Note: Define quadratic function.
Problem 1 Got It? What is the graph of the function? Complete a table of values and graph the function on the canvas. Use colors other than black.
Hint: consider choosing values of x for your table that cancel out the fraction when multiplied. x = 0, 3, and -3 work well.
You may also complete your work on paper or on a whiteboard and upload a clear picture of it to the canvas.
Problem 1 Got It? Graph the parent quadratic function and its transformation on the same plane. Zoom and pan your graph to establish an appropriate viewing window. Consider the relationship between the two functions.
Problem 1 Got It? Reasoning: What can you say about the graph of the function below if a is a negative number?

Take Note: Define minimum value (of a parabola). Be sure to indicate whether the x-coordinate or the y-coordinate represents the minimum value.
Take Note: Define maximum value (of a parabola). Be sure to indicate whether the x-coordinate or the y-coordinate represents the maximum value.
Take Note: Describe why it is not possible for a parabola to have both a maximum value and a minimum value.
Problem 2 Got It? Graph the function on the canvas. Complete this item without Desmos or a graphing calculator. Consider that it is simply a translation of the parent function. You may then check your work at Desmos.
Include relevant graph detail: label axes, indicate units and scale on both axes, and use arrows to represent end behavior as appropriate.

Take Note: Define parabola. Also, sketch a parabola on the canvas.
You may also complete your work on paper or on a whiteboard and upload a clear picture of it to the canvas.
Take Note: The standard form of a quadratic function is as follows:
(Note that a ≠ 0)
One strategy to associate this form with the name standard is to consider the a-b-c pattern it contains.
Another form, vertex form, is so named because it reveals the vertex of the parabola it creates when graphed.
Write the general vertex form of a quadratic function in the response field (assume that a ≠ 0).
HINT: Your equation should include f(x), a, x, h, and k.
