Given a function $f(x)$, if there exists a pair of real numbers $(a,b)$ such that the equation $f(a+x) \cdot f(a-x) = b$ holds for every $x$ in the domain of the function, then the function $f(x)$ is called an "$(a,b)$-type function".

(I) Determine whether the function $f(x) = 4^x$ is an "$(a,b)$-type function", and explain the reason.

(II) Given that function $g(x)$ is a "$(1,4)$-type function", and $1 \leq g(x) \leq 3$ holds when $x \in [0, 2]$, and $g(x) = x^2 - m(x-1) + 1 (m > 0)$ when $x \in [0, 1]$, find the range of values for $m$.
