Question

Me ajudem por favor ​

Answer 1

Resolução:

a) f ( -1 )

f ( x ) = 2x - 2

f ( -1 ) = 2*( -1 ) - 2

f ( -1 ) = 2*( -1 ) - 2

f ( -1 ) = - 2 - 2

f ( -1 ) = - 4

b) f ( 0 )

f ( x ) = 2x - 2

f ( 0 ) = 2*0 - 2

f ( 0 ) = 0 - 2

f ( 0 ) = 0 - 2

f ( 0 ) = -2

c) f ( 1/2 )

f ( x ) = 2x -2

f ( 1/2 ) = 2*( 1/2 ) -2

f ( 1/2 ) = 2*( 1/2 ) -2

f ( 1/2 ) = 1 - 2

f ( 1/2 ) = -1

d) f ( 3 )

f ( x ) = 2x - 2

f ( 3 ) = 2*3 - 2

f ( 3 ) = 6 - 2

f ( 3 ) = 6 - 2

f ( 3 ) = 4

Espero ter ajudado! ;)
