Question

Construír o gráfico da função f(×) =-2×+1 f(-1) f(0) f(1) calcule

Answer 1

Vamos lá

Resolução:

f ( X ) = - 2X + 1
________________

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

f ( - 1 ) = 2 + 1

f ( - 1 ) = 3
_________________

f ( 0 ) = - 2 ( 0 ) + 1

f ( 0 ) = 0 + 1

f ( 0 ) = 1
_________________

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

f ( 1 ) = - 2 + 1

f ( 1 ) = - 1
