Question

1)DADA A FUNÇÃO DEFINIDA POR:
               F(x)=3X-2
CALCULE:
a) F(0)
b)F(1)
c)F(-2)
d)F(-4)

Answer 1

f(x)= 3x-2

f(0)= 3.0-2
f(0)= 0-2
f(0)= -2

f(1)= 3.1-2
f(1)= 3-2
f(1)= 1

f(-2)= 3.(-2)-2
f(-2)= -6-2
f(-2)= -8

f(-4)= 3.(-4)-2
f(-4)= -12-2
f(-4)= -14

Answer 2

$\boxed{f(x)=3x-2}\\ \\ a) \ f(0)=3.0-2=-2\\ \\ b) \ f(1)=3.1-2=1\\ \\ c) \ f(-2)=3.(-2)-2=-8\\ \\ d) \ f(-4)=3(-4)-2=-14$
