Outcomes
10D.QR1.01
Collect data that can be represented as a quadratic relation, from experiments using appropriate equipment and technology or from secondary sources, graph the data and draw a curve of best fit, if appropriate, with or without the use of technology
10D.QR1.02
Determine, through investigation with and without the use of technology, that a quadratic relation of the form y = ax^2 + bx + c (a ≠ 0) can be graphically represented as a parabola, and that the table of values yields a constant second difference.
