How do I solve these kind of questions 1) f(x)=2x3, g(x)=x²1, find (f∘g)(3) (f∘g)(3) = f(g(3)) Find g(3) by substituting x=3 in g(x) g(x)=x²1 g(3)=3²1 g(3)=91 g(3)=8 f∘g(3) = f(g(3)) = f(8) find f(8) by substituting x=8 in f(x) f(x)=2x3 f(8)=2(8)3 f(8)=163 f(8)=19 So f∘g(3) = 19Then, f(x)g(x) = 4x 2 4x 1 = 1 Thus deg( f ⋅ g ) = 0 which is not greater than the degrees of f and g (which each had degree 1) Since the norm function is not defined for the zero element of the ring, we consider the degree of the polynomial f ( x ) = 0 to also be undefined so that it follows the rules of a norm in a Euclidean domainJun 21, 19 · 👍 Correct answer to the question Given f(x) = 2x 3 and g(x) = x 1, what is f g ?
