Solve the separable differential equation

with the condition .

Possible Answers:

Correct answer:

Explanation:

To solve the separable differential equation, we must separate x and y, dx and dy respectively to opposite sides:

Integrating both sides, we get

The rules of integration used were

The constants of integration merged into one.

Now, we exponentiate both sides of the equation to solve for y, and use the properties of exponents to simplify:

To solve for C, we use our given condition:

Our final answer is
