Works for me.
syms x y
f(x)= x+exp(3*x) %input('Enter the function:');
I= [0,1] %input('Enter the interval:');
a=I(1);b=(2);
Df=diff(f,x);
m=(f(b)-f(a))/(b-a);
c=solve(Df==m, x);
c=c(a<c&c<b);
disp('Values of c lying in the interval I are');
disp(double(c));
T=f(c)+m*(x-c);
disp('The tangent Lines at c are');
disp(vpa(y==T,4));
figure
fplot(f,I); grid on; hold on;
fplot(T, I, 'r');
plot(c,double(f(c)), 'ko');
plot(I,double(f(I)), 'm');
xlabel('x'); ylabel('y');

It works fine for me
clear
clc
syms x y
f(x)=x.^2; % modified so code runs here
I=[0 10]; % modified so code runs here
a=I(1);b=(2);
Df=diff(f,x);
m=(f(b)-f(a))/(b-a);
c=solve(Df==m, x);
c=c(a<c&c<b);
disp('Values of c lying in the interval I are');
disp(double(c));
T=f(c)+m*(x-c);
disp('The tangent Lines at c are');
disp(vpa(y==T,4));
figure
fplot(f,I); grid on; hold on;
fplot(T, I, 'r');
plot(c,double(f(c)), 'ko');
plot(I,double(f(I)), 'm');
xlabel('x'); ylabel('y');

I just tried it myself in MATLAB Online, and got all three lines.
When you are on MATLAB Online, what shows up if you command
which plot
which hold

You have your own hold.m that is interfering with the Mathworks command. You need to rename it or delete it or put it in a directory named "private" in the code that needs it.
