In this paper, new results on the approximation of continuous functions by the q-Bernstein polynomials in the case q > 1 are presented. It is shown that if f Ε C[0, 1] and admits an analytic continuation f(z) into {z : |z| < a}, then Bn,q (f; z) → f(z) as n → λ, uniformly on any compact set in {z : |z| < a}.
