Question

considere a funçao do 1 grau
F(x)-3x+2 determine o valor de x para ter
f(x) =0
f(x)=11
f(x)=-1/2

Answer 1

___________________________________

F(x)-3x+2

f(x) =0

f(0)-3.0+2

f(0) = 0 + 2

f(0) = 2

------------------------------

f(x)=11

f(11)-3.11+2

f(11) -33 +2

f(11) = -31

--------------------------------

f(x)=-1/2

f(-1/2)= 3.(-1/2) +2

f(-1/2) = -1,5 + 2

f(-1/2) =  -1,5 + 2

f(-1/2) = 0,5
