$\mathcal\red{♥*♡∞:｡.｡　　KRITIKA}$

Step-by-step explanation:

S (t) = t³ - 1

If t = 1 => S (1) = (1)³ - 1 => 1 - 1 => 0

• :. S (1) = 0

If t = -1 => S (-1) = (-1)³ - 1 => -1 - 1 => -2

• :. S (-1) = -2

If t = 0 => S (0) = (0)³ - 1 => 0 - 1 => -1

• :. S (0) = -1

If t = 2 => S (2) = (2)³ - 1 => 8 - 1 => 7

• :. S (2) = 7

If t = -2 => S (-2) = (-2)³ - 1 => - 8 - 1 => -9

• :. S (-2) = -9

Answer 2

Step-by-step explanation:

Given

S(t) = t³ - 1

if S(1) = 1³ - 1 = 0

if S(-1) = -1³ - 1 = -1 - 1 = -2

if S(0) = 0³ - 1 = 0 - 1 = -1

if S(2) = 2³ - 1 = 8 - 1 = 7

if S(-2) = -2³ - 1 = -8 - 1 = -9
