The two conics bx2 = y and 
= 1 intersect iff-
A
≤ a ≤ 
B
a < – 
C
a> 
D
a < b
Text Solution
Verified by ExpertsThe correct answer is:
A
Substituting x 2 = 
y, the equation of the conic gives the equation a 2 y 2 – by + a 2 b 2 = 0. This has real roots iff b 2 – 4a 4 b 2 ≥ 0 i.e., a 4 ≤ 
giving 
≤ a ≤
