A.
33m 
B.
5 
C.
2 
D.
6
Correct Answer: Option C
Explanation
(int^{1}_{0})(3 – 2x)dx
[3x – x(^2)](_{0} ^{1})
[3(1) – (1)(^2)] – [3(0) – (0)(^2)]
(3 – 1) – (0 – 0) = 2 – 0
= 2
Evaluate (int^{1}_{2})(3 – 2x)dx

[3x – x(^2)](_{0} ^{1})
[3(1) – (1)(^2)] – [3(0) – (0)(^2)]
(3 – 1) – (0 – 0) = 2 – 0
= 2
