Q1. The answer is 19. f(x)=2x+8 g(x)=5 (f + g)(x) = f(x) + g(x) (f + g)(3) = f(3) + g(x) f(3) = 2 * 3 + 8 = 6 + 8 = 14 g(3) = 5 (f + g)(3) = f(3) + g(x) = 14 + 5 = 19 Q2. The answer is -22. f(x)= -2x+8 g(x)=5x (f o g)(x) = f(g(x)) (f o g)(3) = f(g(3)) g(3) = 5 * 3 = 15 (f o g)(3) = f(g(3)) = f(15) = -2 * 15 + 8 = -30 + 8 = -22
