Question

y=x²-2x-8 para x {0,1,2,3,4,5,6}

Answer 1

f(0) = 0² - 2.(0) - 8 =
0 - 0 - 8 = -8

f(1) = 1² - 2(1) - 8 =
1 - 2 - 8 = - 9

f(2) = 2² - 2.(2) - 8 =
4 - 4 - 8 = -8

f(3) = 3² - 2.(3) - 8 =
9 - 6 - 8 = - 5

f(4) = 4² - 2.(4) - 8 =
16 - 8 - 8 = 0

f(5) = 5² - 2.(5) - 8 =
25 - 10 - 8 = 7

f(6) = 6² - 2.(6) - 8 =
36 - 12 - 8 = 16
