xbounds = [0 1];
kbounds = [3.5 4.0];
stepsize = 0.0001;
X = xbounds(1):stepsize:xbounds(2);
K = kbounds(1):0.1:kbounds(2); % reduced k-step size for plot clarity
for j = 1:length(K)
for i = 1:length(X)
fofx(i,j) = K(j) * X(i) * (1 - X(i));
end
end
figure
for k = 1:length(K)
plot(X,fofx(:,k))
hold on
end
legend(num2str(K'),'location','south')
xlabel('x')
ylabel('f(x)')
hold off

For example,
k=linspace(3.5,4.0,5);
x=0:0.0001:1;
for i=1:numel(k)
f =k(i).*x.*(1-x);
plot(x,f); xlabel x; ylabel f(x)
hold on
end
hold off; legend("k = "+k)
