Question

qual o valor numérico de f(x)=-3x+4 para, f(0)+f(1)-f(1/2) / f(1/3)

Answer 1

$f(0)= -3.0 +4 \\ 0+4 \\ 4 \\ \\ f(1)=-3.1+4 \\ -3+4 \\ 1 \\ \\ f( \frac{1}{2} )=-3. \frac{1}{2} +4 \\ - \frac{3}{2} +4 \\ -3+8 \\ 5 \\ \\ f( \frac{1}{3}) =-3. \frac{1}{3} +4 \\ \frac{-3}{3} +4 \\ -1+4 \\ 3 \\ \\ \frac{f(0)+f(1)-f( \frac{1}{2} )}{f( \frac{1}{3})} \\ \frac{4+1-5}{3} \\ \frac{5-5}{3} \\ \frac{0}{3} \\ 0$
