Question

construa as tabelas e os graficos das funções:f(x)=3x-2. E. f(x)=-2x+1

Answer 1

$f(x)=3x-2 3x-2=0 \\ \\ 3x=2 \\ \\ x = \frac{2}{3}$

y=0 x=$\frac{2}{3}$

$f(0)=3.0-2 \\ \\ f(0)=-2 \\ \\ x=0 y=-2$

$f(x)=2x+1 \\ \\ 2x+1=0 \\ \\ 2x=-1 \\ \\ x=- \frac{1}{2} \\ \\ y=0 X=- \frac{1}{2} \\ \\ F(0)=2.0+1 \\ \\ F(0)=1 \\ \\ x=0 y=1$

f(x)=3x-2

x|y

f(x)=2x+1

-1/2|0
