Question
Hint:
When x = a ,f(a) = 0 or when x = b , f(b) = 0
Substitute the respective values if f(z) and f(y) by taking x as z and y in the equation and find the answer.
The correct answer is:
When x = a , Substitute the value of x in equation 1
f(y) = 
and f (z) = 
Substitute these values in equation 2 we get
