Resolver ese problema

Answer 1

Explicación paso a paso:

1

$f (\frac{1}{ 3} ) = { (\frac{1}{3} )}^{2} - 5( \frac{1}{3} ) + 2 \\ \frac{1}{9} - \frac{5}{3} + 2 = \frac{1}{9} - \frac{15}{9} + \frac{18}{9} = \frac{4}{9}$

2

$f( - \sqrt{6} ) = {( - \sqrt{6} )}^{2} - 5( - \sqrt{6} ) + 2 \\ 6 + 5 \sqrt{6} + 2 = 8 + 5 \sqrt{6}$

$f(8 + 5 \sqrt{6} ) = 6(8 + 5 \sqrt{6} ) - 8 \\ 48 + 30 \sqrt{6} - 8 = 40 + 30 \sqrt{6} = 10(4 + 3 \sqrt{6} )$

3

$f(0) = {0}^{2} - 5(0) + 2 = 2 = vacio$

4

$f( - 2) = {( - 2)}^{2} - 5( - 2) + 2 \\ 4 + 10 + 2 = 16$

$f(16) = 6(16) - 8 = 96 - 8 = 88$
