Daniela tried to solve the differential equation dy d: 9 = 22.e-y. This is her work: 9 = 22. e-y d Step 1: Je=”dy= [ 23 dx Step 2: . ev = x² + a Step 3: e-*= -+C Step 4: In(e-y) = ln(-x? + C) Step 5: -y= ln(-22 +.C) Step 6: y = – In(-22 +C) Is Daniela’s work correct? If not, what is her mistake? Choose 1 answer: Step 1 is incorrect. The separation of variables wasn’t done correctly. © Step 2 is incorrect. Daniela didn’t integrate e correctly. 0 Step 4 is incorrect. The right-hand side of the equation should be ln(-2°) + C.
