Consider the following statements:I. \dfrac{dy}{dx} =.II. is the solution of Which of the statements given above is/are correct?
Options
- AI only
- BII only
- CBoth I and II
- DNeither I nor II
Correct answer
C. Both I and II
Step-by-step solution
For Statement I:
Given
Differentiating with respect to :
Also, e^{2x}(2x + 1) y\left(2 + \dfrac{1}{x}\right), Statement I is correct.
For Statement II:
Given
Differentiating with respect to :
\dfrac{dy}{dx} = \ln| c = \ln|x| + 1 + c
Since and II are correct.
