How can I plot a for loop?

Can someone tell me what's wrong with this code? It is only plotting at x=6 because the loop obviously ends there.
e=2.718;
for x=-2:1:6
if x<-1
y=e.^(x+1)
elseif x>=-1 && x<5
y=2+cos(pi.*x)
elseif x>=5
y=10.*(x-5)+1
else
fprintf('answer not given')
end
end
x=-2:6;
plot(x,y)
Thanks you

You’re not subscripting either ‘x’ or ‘y’. That’s important because ‘x’ is negative and zero, so it can’t be used as indices. Also, the lengths of both vectors have to be the same.
A few tweaks and your code works:
e=2.718;
x=-2:1:6;
for k1 = 1:length(x)
if x(k1)<-1
y(k1)=e.^(x(k1)+1);
elseif x(k1)>=-1 && x(k1)<5
y(k1)=2+cos(pi.*x(k1));
elseif x>=5
y(k1)=10.*(x(k1)-5)+1;
else
fprintf('\nanswer not given\n')
y(k1) = NaN;
end
end
x=-2:6;
plot(x,y)
