Let x be the particular solution

for and .

Step-by-step explanation:

The given differential equation is

Rearranging it as

where C is constant.

The initial condition is f(-1)=-1, i.e for x=-1, y=-1.

So, by using the initial condition to get the value of constant:

From equation (i), we have

As y=f(x), so the required particular solution

Now, determining the domain of the function

As for a real value output, the term under square root must be positive.

So,

Therefore, the domain of the function is

Hence, for and .

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
