Question

f (x)= -x+1 para x= -2,-1,0,1,2

Answer 1

f(x) = - x + 1

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

f(-2) = 2 + 1

f(-2) = 3

-------------------------------------

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

f(-1) = 1 + 1

f(-1) = 2

---------------------------------------------

f(0) = - 0 + 1

f(0) = 1

-----------------------------------------------

f(1) = - 1 + 1

f(1) = 0

-----------------------------------------------

f(2) = - 2 + 1

f(2) = - 1
