Verify that the indicated function y = p(x) is an explicit solution of the given first-order differential equation.
y' = 2xy²; y = 1/(16 - x²)
When y= 1/(16 - x²),
y' =
Thus, in terms of x,
2xy² =
Since the left and right hand sides of the differential equation are equal when 1/(16-x2) is substituted for y, y = 1/(16-x2) is a solution.
Proceed as in Example 6, by considering simply as a function and give its domain. (Enter your answer using interval notation.)
Then by considering as a solution of the differential equation, give at least one interval I of definition.
