function fx = p02_fun ( n, x )

%*****************************************************************************80
%
%% p02_fun() evaluates the integrand for problem 2.
%
%  Discussion:
%
%    The integrand is discontinuous at X = 0.3.
%
%  Interval:
%
%    0 <= x <= 1
%
%  Integrand:
%
%    if ( x < 0.3 )
%      f(x) = 0
%    else
%      f(x) = 1
%
%  Antiderivative:
%
%    if ( x < 0.3 )
%      g(x) = 0
%    else
%      g(x) = X - 0.3
%
%  Exact Integral:
%
%    0.7
