This Building an Explicit Quadratic Function by Composition assessment also includes:
Use equivalent expressions to reveal information about their graphs. Pupils verify that two quadratic functions are equivalent. By comparing the two expressions, they determine the vertex, the zeros, the y-intercept, and the direction it opens. Scholars analyze compositions to determine their order and the resulting transformations in building the function.
