Question

ache o F(2) e o F(-1/3) respectivamente. ​

Answer 1

Resposta:

$f(2) = {2}^{2} - 3 \times 2 + 4 \\ f(2) = 4 - 6 + 4 \\ f(2) = 2$

$f( - \frac{ 1}{3} ) = ( - \frac{1}{3} ) ^{2} - 3 \times - \frac{1}{3} + 4 \\ f( - \frac{ 1}{3} ) = \frac{1}{9} + 1 + 4 \\ f( - \frac{ 1}{3} ) = \frac{1}{9} + 5 \\ f( - \frac{ 1}{3} ) = \frac{1}{9} + \frac{45}{9} \\ f( - \frac{ 1}{3} ) = \frac{46}{9}$
