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
