Question

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

Answer 1

f(x) = 2x - 1

f(-2) = 2 . (-2) - 1

f(-2) = - 4 - 1

f(-2) = - 5

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

f(-1) = 2 . (-1) - 1

f(-1) = - 2 - 1

f(-1) = - 3

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

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

f(0) = - 1

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

f(1) = 2 . (1) - 1

f(1) = 2 - 1

f(1) = 1

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

f(2) = 2 . (2) - 1

f(2) = 4 - 1

f(2) = 3
