Question

O zero da função f(x)=3x+2 f(x)=4x-3 y=2x+3

Answer 1

f(x) = 3x + 2

3x + 2 = 0

3x = - 2

x = - 2/3

f(x) = 4x - 3

4x - 3 = 0

4x = 3

x = 3/4

y = 2x + 3

2x + 3 = 0

2x = - 3

x = - 3/2

Answer 2

Oi....

a)

f(x) = 3x + 2

f(x) = 0

3x + 2 = 0

3x = - 2

x = -2/3

b)

f(x) = 4x - 3

f(x) = 0

4x - 3 = 0

4x = 3

x = 3/4

c)

y = 2x + 3

y = 0

2x + 3 = 0

2x = - 3

x = - 3/2
