I can only recreate the error in MATLAB Online if I modify your code so that the fun does not use x in the equation. Otherwise your code works fine. Perhaps you use fplot somewhere else in your code. Have you shared all your code?
fun = @(x) exp - 3.^2 + 26;
fplot(fun,[0 5])
grid on
Warning: Error updating FunctionLine.

For me it works:
fun = @(x) exp(-x) - 3.*x.^2 + 26
fun = function_handle with value:
@(x)exp(-x)-3.*x.^2+26
fplot(fun,[0 5])
grid on
So if this fails for you, you are running another code. maybe you have redefined exp()?
