POWER OR SUPPORTING?
Supporting
describes the relationship between
the coefficients and the roots of a
quadratic equation.
solves equations transformable to
quadratic equations (including
rational algebraic equations).
solves problems involving quadratic
equations and rational algebraic
equations.
illustrates quadratic inequalities

solves problems involving quadratic
inequalities.
models real-life situations using
quadratic functions.
represents a quadratic function using:
(a) table of values; (b) graph; and (c)
equation.
transforms the quadratic function
defined by y = ax2 + bx + c into the
form y = a(x – h)2 + k.
graphs a quadratic function: (a)
domain; (b) range; (c) intercepts; (d)
axis of symmetry; (e) vertex; (f)
direction of the opening of the
parabola.
analyzes the effects of changing the
values of a, h and k in the equation y =
a(x – h)2 + k of a quadratic function on
its graph
determines the equation of a
quadratic function given: (a) a table of
values; (b) graph; (c) zeros.
