data = {{4, 4}, {4, 25}, {25, 63}, {63, 147}, {147, 285}, {285,
361}, {361, 405}, {405, 471}, {471, 420}, {420, 430}, {430,
420}, {420, 475}, {475, 435}, {435, 480}};
I have data like above , data Pn as x and P(n+1) as y
I am using Fit
to make the plot, but the plot only shown dots not line:
line = Fit[data, {1, x}, x]
parabola = Fit[data, {1, x, x^2}, x]
im trying to compare the linear and quadratic data on my cases
