Question

2-Dada a função F(x)=-2x+3, calcule:
A) F(x)=3
B)F(x)=1
C)F(x)=-7
D)F(x)=0​

Answer 1

Explicação passo-a-passo:

a) 3 = -2x +3

3-3= -2x

0= -2x

0/-2=x

x=0

b) 1 = -2x +3

1 -3=-2x

-2=-2x

-2/-2=x

x= +1

c) -7 = -2x +3

-7 -3= -2x

-10 = -2x

-10/-2=x

x= + 5

d) 0 = -2x +3

2x= 3

x= 3/2
