{"library":"Scipy","prompt":"Problem:\nI have a set of data and I want to compare which line describes it best (polynomials of different orders, exponential or logarithmic).\nI use Python and Numpy and for polynomial fitting there is a function polyfit(). But I found no such functions for exponential and logarithmic fitting.\nHow do I fit y = A*exp(Bx) + C ? The result should be an np.array of [A, B, C]. I know that polyfit performs bad for this function, so I would like to use curve_fit to solve the problem, and it should start from initial guess p0.\nA:\n<code>\nimport numpy as np\nimport scipy.optimize\ny = np.array([1, 7, 20, 50, 79])\nx = np.array([10, 19, 30, 35, 51])\np0 = (4, 0.1, 1)\n</code>\nresult = ... # put solution in this variable\nBEGIN SOLUTION\n<code>\n"}
