Getting two windows using figure & subplot when I only want one?

I'm using the subplot feature and I'm getting two windows when I only want one? The issue I think is in the first few lines, I'm including everything just in case.

hold on
figure('Name','Question 8','position',[50 50 1000 600])
subplot(2,3,1)% Graph A
x = linspace(0,5);
y = exp(x);
plot(x,y,'bl')
axis([0 5 0 150]) 
xlabel('x axis')
ylabel('y axis')
title('A = [3] e^{x}')
%****************************************
subplot(2,3,2)% Graph B
y = log(x);
plot(x,y,'bl')
axis([0 5 -3 2]) 
xlabel('x axis')
ylabel('y axis')
title('B = [5] ln x')
%****************************************
subplot(2,3,3)% Graph C
y = log(1./x);
plot(x,y,'bl')
axis([0 5 -2 3]) 
xlabel('x axis')
ylabel('y axis')
title('C = [6] ln ^{1}/_{x}')
%****************************************
subplot(2,3,4)% Graph D
x = linspace(-5,5);
y = exp(-x);
plot(x,y,'bl')
xlabel('x axis')
ylabel('y axis')
axis([-5 5 0 150]) 
title('D = [4] e^{-x}')
%****************************************
subplot(2,3,5)% Graph E
x = linspace(1,5);
y = 1./x.^2;
plot(x,y,'bl')
xlabel('x axis')
ylabel('y axis')
axis([1 5 0 1])
title('E = [1] ^{1}/_{x}')
%****************************************
subplot(2,3,6)% Graph F
y = 1./x;
plot(x,y,'bl')
xlabel('x axis')
ylabel('y axis')
axis([1 5 0 1])
title('F = [2] ^{1}/_{x^2}')

Answer 1

Figured this one out also.

by adding

hold on
hold off

I inadvertently added a new figure window. Removing it fixed my issue.

Answer 2

[KALYAN ACHARJYA]

I think before first two lines, there is another figure (As "hold on" statement is there), so definitely return the 2 figure window

%Check Following lines
hold on
figure('Name','Question 8','position',[50 50 1000 600])
