You need to use dot indexing since the values passed in will be in an array. Since this looks like a HW problem, I encourage you to play with ".*" and "./" and use the following link to help you with the natural log.

yeah but the problem is that i did try to make it work and i failed if u can help me with the code it will be wonderful

[Mitch Lautigar]

% numerator ./ denominator

y = ( 2.* exp(x) ) ./ ()

%you can handle the denominator. Note how I'm using parenthesis and spaces to make things easier to see.

so after i write the equation and in order to get a gragh i just use plot(x,y) right?

[Mitch Lautigar]

yes
