Plotting a function and a horizontal line segment
Mostra commenti meno recenti
I need to plot f(x) = -ln(x+0.01)+e^x and g(x)=f(0) from x=0 to the second intercept point. I can plot the f(x) function, I just don't know how to plot both of them together (and how I plot a horizontal line segment). Thanks

Try this:
f = @(x) exp(x) - log(x+0.01);
x2nd = fzero(@(x) f(x)-f(0), 5); % Find Second ‘x’ At ‘f(0)’
x = linspace(0, 2);
y = f(x);
figure(1)
plot(x, y)
hold on
plot([0 x2nd], f(0)*[1 1], '-r')
hold off
grid
