• Identify and describe the characteristics of quadratic expressions in
one variable. 3

• Recognise quadratic function as many-to-one relation, hence, 3
describe the characteristics of quadratic functions.

• Investigate and make generalisation about the effect of changing the 4
values of a, b and c on graphs of quadratic functions, f (x) = ax + bx + c.
