Question

04. determine a raíz e o coeficiente linear em cada função
a)y=2x -1
b)f(x)=x-3
c)f(x)=x
d)f(x)= -3x+1
me ajudem por favor​

Answer 1

a)y=2x -1

2x-1=0 => 2x=1 => x=1/2 (raíz)

b= -1 (coef. linear)

b)f(x)=x-3

x-3=0 => x=3 (raíz)

b= -3 (coef. linear)

c)f(x)=x

x=0 (raíz)

b = 0 (coef. linear)

d)f(x)= -3x+1

-3x+1=0 => 3x=1 => x=1/3 (raíz)

b= 1 (coef. linear)

Answer 2

Resposta:

a)y=2x -1

2x-1=0 => 2x=1 => x=1/2 (raíz)

b= -1 (coef. linear)

b)f(x)=x-3

x-3=0 => x=3 (raíz)

b= -3 (coef. linear)

c)f(x)=x

x=0 (raíz)

b = 0 (coef. linear)

d)f(x)= -3x+1

-3x+1=0 => 3x=1 => x=1/3 (raíz)

b= 1 (coef. linear)
