... (a) 2(f+g)(x) = 2(f (x) + g(x)) = 2(x3 + 2x2 + (π + (−π))x + (2 + 14)) = (2 · 1)x3 + (2 · 2)x2 + (2 · 16) = 2x3 + 4x2 + 32. (b) 6(f-g)(x) = 6(f (x) − g(x)) = 6(x3 + 2x2 + (π +− (−π))x + (2 + (−14)) = (6 · 1)x3 + (6 · 2)x2 + (6 · 2π)x + (6 · (−12)) = 6x3 + 12x2 + 12πx − 72. 5. Let V be a vector space ...
