Answer the following questions on the basis of the information given below:
f1(x)= x for 0
= 1 for x = 1
= 0 otherwise
f2(x)= f1(-x) for all x
f3(x)= -f2(x) for all x
f4(x)= f3(-x) for all x
Q1) How many of the following products are necessarily zero for every x
f1(x)f2(x), f2(x)f3(x), f2(x)f4(x)?
(1)0 (2)1 (3)2 (4)3
Q2) Which of the following is necessarily true?
(1)f4(x) = f1(x) for all x (2)f1(x) = -f3(-x) for all x
(3)f2(-x) = f4(x) for all x (4)f1 (x) + f3(x) = 0 for all x
