The answer to your question is the third option
Step-by-step explanation:
a) 0.023x³ + 0.4x² - 2.1x + 8.3
0.023(2)³ + 0.4(2)² - 2.1(2) + 8.3
0.023(8) + 0.4(4) - 2.1(2) + 8.3
0.184 + 1.6 - 4.2 + 8.3
10.084 - 4.2
5.884
b) 0.023(4)³ + 0.4(4)² - 2.1(4) + 8.3
0.023(64) + 0.4(16) - 8.4 + 8.3
1.472 + 6.4 - 8.4 + 8.3
16.172 - 8.4
7.772
