1.	If f(x) = 2x and g(x) = \(\frac{1}{2^x}\) then (fg)(x) is: (a) 1 (b) 0 (c) 4x (d) \(\frac{1}{4^x}\)
Answer» (a) 1 (fg) x = f(x) g(x) = 2^xx \(\frac{1}{2^x}\) = 1

If f(x) = 2x and g(x) = \(\frac{1}{2^x}\) then (fg)(x) is: (a) 1 (b) 0 (c) 4x (d) \(\frac{1}{4^x}\)

Answer»

(a) 1

(fg) x = f(x) g(x) = 2^xx \(\frac{1}{2^x}\) = 1
