    FUNCTIONS

    A function is a type of relation where each object in the domain has only one imagein the codomain.

    A one-to-one relation and many-to-one relation can be a function.

    Quadratic equations and their roots

    o A quadratic equation is an algebraic equation which has only one unknown and thehighest power of the unknown is 2.

    o The general form of quadratic equation is : ax2 + bx + c = 0, where a, b and c areconstants.

    o The values which satisfy a quadratic equation are known as the roots.o The roots can be determined by

    (a) factorization method.

    Conditions for different types of roots

    o Given a quadratic equation ax2 + bx + c = 0, if(a) b

    (b) b2

    4ac = 0, the equation has two real and equal roots,

    (c) b2

    4ac < 0, the equation has no roots.

    (d) b2

    4ac 0, the equation has real roots.

    o The expression b2 4ac is known as the discriminant of a quadratic equation.
