Question

Determine os zeros das função a seguir :
a)y=1-x
b)y=x-2
c)y=2x-4
d)y=x/2-3
e)y=3-3​

Answer 1

a)y=1-x   y=1-(1)   y=1-1   y=0

1-x=0

-x=-1*(-1)

x=1

b)y=x-2    y=2-2     y=0

x-2=0

x=2

c)y=2x-4   y=2*2-4 y=4-4    y=0

2x-4=0

2x=4

x=2

d)y=x/2-3  y=6/2-3   y=3-3   y=0

x/2-3=0

x/2=3

x=3*2

x=6

e)y=3-3

y=0

Todasas respoatas terminam em 0
