The number of continuous function f:[0,1] [0,1] such that f ( x ) < x ² for all x and ₀¹ f ( x ) d x = 1 3 is :
Options
- A0
- B1
- C2
- Dinfinite
Correct answer
A. 0
Step-by-step solution
f ( x ) is always positive for x [0,1] array c f ( x ) < x ² ₀¹ f ( x ) d x < ₀¹ x ² I < 1 3 array But it is given that I = 1 3 which is not possible
