I am having issues with plotting.
my function is
y2 = (x-1)(ln((3^.5)/2)*x-ln(3/8));
is not running because of ln but I have changed to log. still an error of some operator.
x range of [1, 3]
y2 = (x-1)(log((3^.5)/2)*x-log(3/8));
plot(x,y2)
Thanks.

It is missing a multiplication operator:
y2 = (x-1)(log((3^.5)/2)*x-log(3/8));
↑
Try this:
y2 = (x-1).*(log((3^.5)/2).*x-log(3/8));
This also uses element-wise operations. See Array vs. Matrix Operations for an extended discussion.
