y=exp(x)
fplot(y)

How is it not working?
If you get an error, share the full error mesage i.e all of the red text.
if something else, then specify in detail.

Ran in:
Alt syntax for using fplot is this one:
FUN = @(x)exp(x);
fplot(FUN), grid on
figure
% Or a bit better controlled way by specifying the range of x values
fplot(FUN, [-2, 2])
grid on

I want to know the reason why fplo(y) is not working and we have to define it as f=@exp(x)

It is likely that you have saved one of your MATLAB files by fplot.m name or you have named/stored one of your variables by fplot.
(1) Run this command:
>> which fplot % See whether it is a MATLAB builtin function or variable or you saved M-file
If it is one of your saved M-files, just rename your M-file, e.g.: fplot_1.m
(2) Run this command:
>> clear all
(3) Now, you should be able to execute fplot() fcn.
All the best.
