Resposta:

Esquema:

a)

$f(x) = \dfrac{3x}{2} + \dfrac{1}{4} \\\\f( 1 ) = \dfrac{3\times 1} {2} + \dfrac{1}{4} \\\\f( 1 ) = \dfrac{3} {2} + \dfrac{1}{4} \\\\f( 1 ) = \dfrac{6} {4} + \dfrac{1}{4} \\\\f( 1 ) = \dfrac{7} {4}$

b)

$f(x) = \dfrac{3x}{2} + \dfrac{1}{4} \\\\f( 2 ) = \dfrac{3\times 2} {2} + \dfrac{1}{4} \\\\f( 2 ) = \dfrac{6} {2} + \dfrac{1}{4} \\\\f( 2 ) = \dfrac{12} {4} + \dfrac{1}{4} \\\\f( 2 ) = \dfrac{13} {4}$
