Classify each function as a power function, root function, polynomial (state its degree), rational function, algebraic function, trigonometric function, exponential function, or logarithmic function.
(a) f(x) = log2x
(b) g(x) = 4√x
(c) h(x) = 2x3 / 1 - x2
(d) u(t) = 1 - 1.1t + 2.54 t2
(e) v(t) = 5t
(f) w(θ) = sin θ cos2θ
