How to average a range of output from a graphical equation?

1 view (last 30 days)
Hi guys,
I have the following equation and 2dgraph:
x = linspace(0,10);
y = @(x) 2+(2.*log(x));
hold on
a) How can I find the average between the two points? b) How can I plot a horizontal bar ( link ) spanning the range of x at the level of average between the two points?
Thank you

mask = x >= 3 & x <= 6;
validx = x(mask);
ybar = mean( y(validx) );
plot(validx([1 end]), [ybar ybar], 'k')
