Problem 2. Verify that each given function is a solution of the given differential equation.
Throughout these problems, primes denote derivatives with respect to x.
(a) y' = 3x2; y = x³ + 7
(b) y" = 9y; yı = er, y½ = e-3z
(c) y' = y+ 2e¬²: y= e* – e¯
(d) x?y" + xy – y = ln x; y1 = x – In x, y2 = ! - Inx
