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
