#2579 — Re: question about plotting

Clear[a, b, c, x]

data = Table[{x, 3 x^2 - 5 x + 7 + 10*RandomReal[]}, {x, 0, 5, .1}];

f[x_] = Fit[data, {1, x, x^2}, x];

Plot[f[x], {x, 0, 5}, Epilog -> {Red, Point[data]}]

Show[ListPlot[data, PlotStyle -> Red], Plot[f[x], {x, 0, 5}]]

=============
Hello,
I would like to combine plot od datapoints in one dimension(for this I
use ListPlot[data]) with fitted function ( f[r] ). Do you know how to
do this?

Best wishes
Krzysztof
