trying to get the second intercept on my matlab code.

%Code for plotting cross sectional area.

d=0:0.1:5;

fx = -1*log(d + 0.01) + exp(d);

gx = (-1*log(0 + 0.01)+exp(0));

y1=gx;

x1=-0.5;

x2=5;

trough= plot(d,fx,[x1, x2], [y1, y1]);

axis([-0.5 5 0 10]);

title(' Cross sectional Area Of Trough');

xlabel(' Horizontal Distance');

ylabel('Cross sectional Area');

min(fx);

Cross sectional Area Of Trough 10 0.5 0.5 1.5 2.5 3.5 4.5 Horizontal Distance
