Answer 1

Olá ;-;

f(x)= -3x+1
f(-2)= -3.(-2)+1
f(-2)=6+1
f(-2)=7

Letra A

Answer 2

f(x) = -3x + 1
a) f(7)=-3(7)+1
f(7)=-21+1
f(7)=-20

b)  f(4)=-3(4)+1
 f(4)=-12+1
 f(4)=-11

c) f(12)=-3(12)+1
f(12)=-36+1
f(12)=-35

d) f(6)=-3(6)+1
f(6)=-3(6)+1
f(6)=-18+1
f(6)=-17

e) f(8)=-3(8)+1
f(8)=-24+1
f(8)=-23

f) f(9)=-3(9)+1
 f(9)=-27+1
