Explanation / Answer
14.)
a.) Since, each value in x is either greater that 2 or less than 5. Therefore,
(x>2)|(x<5) = [1 1 1 1 1]
b.)Since, only last three values in x is less than 6. Therefore,
x(x<6) = [2 1 4]
c.) Since, every value in x is less than or equal to 8. Therefore,
y(x<=8) = [8 3 5 2 7]
d.) Except last value of x i.e., 4, all other values are either less than 3 or greater than or equal to 6. Therefore,
x((x<3) | (x>=6)) = [6 6 2 1]
e.) Since, there is no value in x which is less than 4 and greater than or equal to 7. Therefore,
y((x<4) & (x>=7)) = []
