Question

determinar o valor de m , tal que a função f seja afim : a) f(9m+3)x-2 b) f(x)=3+(m2-16)x c) f(x)=(5m2-m)x+3

Answer 1

a) 9m+3<>0, logo:
$m < > - \frac{1}{3}$

b) m2-16<>0, logo:
${m}^{2} - 16 < > 0 \\ m < >4 \: e \: m < > - 4$

c) 5m2-m<>0, logo:
$5 {m}^{2} - m < > 0 \\ m(5m - 1) < > 0 \\ m < > 0 \: e \: m < > \frac{1}{5}$
