QFV.02 demonstrate an understanding of functions, and make connections between the numeric, graphical, and algebraic representations of quadratic functions;
QFV.03 solve problems involving quadratic functions, including those arising from real-world applications.

Specific Expectations:

QF3.01 collect data that can be modelled as a quadratic function, through investigation with and without technology, from primary sources, using a variety of tools, or from secondary sources, and graph the data (Sample problem: When a 3 × 3 × 3 cube made up of 1 × 1 × 1 cubes is dipped into red paint, 6 of the smaller cubes will have 1 face painted. Investigate the number of smaller cubes with 1 face painted as a function of the edge length of the larger cube, and graph the function.);
QF3.02 determine, through investigation using a variety of strategies, the equation of the quadratic function that best models a suitable data set graphed on a scatter plot, and compare this equation to the equation of a curve of best fit generated with technology.
