Q.1) If f(x) = (x – 1) (x – 2) (x – 3) find the values of
(i) f(1) (ii) f(2) (iii) f(3) (vi) f(0).

f(x) = (x – 1) (x – 2) (x – 3)
(i) f(1) = (1 - 1) ( 1 - 2) (1 - 3)
f(1) = (0) (-1) (-2) = 0

(ii) f(2) = ( 2 - 1 ) ( 2 - 2) ( 2- 3)
f(2) = (1) (0) (-1) = 0

(iii) f(3) = (3 -1) (3 - 2) (3 - 3)
f(3) = (2) (1) (0) = 0

(vi) f(0) = (0 - 1) ( 0 - 2) ( 0- 3)
f(0) = (-1) (-2) (-3) = -6
