The differential equation | d y d x | + | y | + 3 = 0 admitsa)Infinite...
Explanation:
Given differential equation is |d/dx| |y| + 3 = 0
Let's consider two cases:
Case 1: d/dx > 0 (when y > 0)
In this case, the differential equation becomes d/dx(y) + 3 = 0
Solving this differential equation gives y = ce^(-3x), where c is a constant
Case 2: d/dx < 0="" (when="" y="" />< />
In this case, the differential equation becomes d/dx(-y) + 3 = 0
Solving this differential equation gives y = -ce^(3x), where c is a constant
Conclusion:
As we can see, the solutions obtained in the two cases are not continuous at y = 0, which means there is no solution that satisfies the given differential equation for all values of x. Therefore, the correct answer is option B, i.e., there is no solution.
