Answer 1

Answer:

see explanation

Step-by-step explanation:

Evaluate u for each value of n by substituting value of n into u, that is

n = - 1 → u = - 5(- 1)² + 4(- 1) = - 5(1) - 4 = - 5 - 4 = - 9

n = 0 → u = - 5(0)² + 4(0) = 0 + 0 = 0

n = 1 → u = - 5(1)² + 4(1) = - 5 + 4 = - 1

n = 2 → u = - 5(2)² + 4(2) = - 5(4) + 8 = - 20 + 8 = - 12

Thus

   n          u

   - 1         - 9

     0          0

      1          - 1

      2          - 12
