The functions f and g are defined by f(x) = mx + 2 and g(x) = kr – 3 respectively. If
fg = gf, find the relation between m and k.​

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
