Abstract: In this paper, a quantitative estimation on the number of zeros of the function $ f \circ g(z) - \alpha (z)$ is derived, where $ f$ and $ g$ are transcendental entire functions and $ \alpha (z)$ a nonconstant polynomial. As an application of this and a further step towards an affirmative answer to a conjecture of Baker, a quantitative estimation on the number of period points of exact order $ n$ of $ {f_n}$ ($ n$th iterate of $ f$) is obtained.
