Question

quem poder dar aquela ajuda :)​

Answer 1

Resposta:

f(x)=6x+3

a) f(-2)=6*(-2)+3 =-12+3=-9

b) f(0)=6*(0)+3 =0+3=3

c) f(-3)=6*(-3)+3 =-18+3=-15

d) f(2/4)=6*(2/4)+3 =3+3=6

Answer 2

Resposta:

a)

F( -2) = ?

$\sf F(x) = 6x + 3 \\F(-2) = 6.(- 2) + 3\\F(-2) = - 12 + 3 \\\framebox {F( - 2) = - 9 }$

b)

F(0) = ?

$\sf F(x) = 6x + 3 \\F(0 ) = 6. 0 + 3\\F(0) = 0 + 3 \\\framebox {F( 0) = 3 }$

c)

F(-3) = ?

$\sf F(x) = 6x + 3 \\F(- 3 ) = 6. ( - 3) + 3\\F(- 3) = - 18 + 3 \\\framebox {F( - 3) = - 15 }$

d)

F(2/4) = ?

$\sf F(x) = 6x + 3 \\F(2/4 ) = 6. (2/4) + 3\\F(2/4) = 12/4 + 3 = F(2/4) = 3 + 3 \\\framebox {F( 2/4) = 6 }$
