Question

Dada a funçao afim f(x)=-2×+3 , determine :

a) f(1)=

b) f(0)=

Answer 1

a)f(1)=

x = 1

f(x) = -2x + 3

f(1) = - 2(1) + 3

f(1) = - 2 + 3

f(1) = + 1

f(1) = 1

b)f(0)=

x = 0

f(x) = - 2x + 3

f(0) = - 2(0) + 3

f(0) = - 0 + 3

f(0) = 3

Answer 2

Oi !

Solução:

f ( X ) = - 2X + 3
______________

f ( 1 ) = - 2 ( 1 ) + 3

f ( 1 ) = - 2 + 3

f ( 1 ) = 1

Próxima...

f ( 0 ) = - 2 ( 0 ) + 3

f ( 0 ) = 0 + 3

f ( 0 ) = 3
