Verify that the indicated function y = g(x) is an explicit solution of the given first-order differential equation. y' = 2xy2; y = 1/(16 – x2) When y = 1/(16 – x²), 2x y' = (16 – 2)2 Thus, in terms of x, 2x 2xy2 : (16 – x²)² | Since the left and right hand sides of the differential equation are equal when 1/(16 – x-) is substituted for y, y = 1/(16 – x<) is a solution. Proceed as in Example 6, by considering simply as a function and give its domain. (Enter your answer using interval notation.) y=0(x)y= ) = »(x)is(-,-4)U(-4,4)U(4,00) Then by considering o as a solution of the differential equation, give at least one interval I of definition.
