Question

Dada função definida por f(x) = -2x + 1 , calcule f(0), f(1), f(-1)

Answer 1

F(x) = - 2x + 1

F(0) = - 2 . 0 + 1

F(0) = 1

F(1) = - 2 . 1 + 1

F(1) = - 2 + 1

F(1) = - 1

F(-1) = - 2 . (-1) + 1

F(-1) = 2 + 1

F(-1) = 3

Answer 2

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


F(1)=-2(1)+1
F(1)=-2+1
F(1)=1

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