Hi guys, I'm trying to plot this function on matlab but it isn't working as it should.

The function is:

x=-10:0.1:10;
y=1500*exp(x)-2264+475*((exp(x)-1)/x);
plot(x,y)

That is the code. What do you mean with the content of the images did not make it? I can see the images.

The function I try to plot is

f(x)=1500*e^x+475*(e^x-1)/x-2264

To us, what shows up instead of images is:

The function is: Hj-SsrpFS0C4huXdg2I49Q.png

I can see that that is actually a reference to an image on prtscr.com but when I go to visit the image I am told "403 forbidden". I would guess that the images are set to private.

The images you posted don't show up for me, either.

Your code ran for me, and yielded this figure:

I think you might have wanted

x=-10:0.1:10;
y=1500*exp(x)-2264+475*((exp(x)-1)./x);
plot(x,y)

Note that I added a dot to the division sign, to make it an element-wise.
