Evaluate int 1 2 3 - 2x dx - JAMB Mathematics 2011 Question
Evaluate \(\int^{1}_{2}\)(3 - 2x)dx
A
33m
B
5
C
2
D
6
correct option: c
\(\int^{1}_{0}\)(3 - 2x)dx
[3x - x2]o
[3(1) - (1)2] - [3(0) - (0)2]
(3 - 1) - (0 - 0) = 2 - 0
= 2
[3x - x2]o
[3(1) - (1)2] - [3(0) - (0)2]
(3 - 1) - (0 - 0) = 2 - 0
= 2
