Value of the parameter 'a' such that area bounded by y = x2− 3 and the line y = ax + 2, attains it's minimum value is
A
-1
B
1
C
0
D
None of these
Answer
0
Explanation
Solution
The lines y = ax + 2 are concurrent at (0, 2). Thus bounded area is minimum provided a = 0. Because the area tend to increase if we take 'a' to be negative or positive
