Can anybody help how to write Matlab code for backward bifurcation

I am working on a paper ,I have seen below graphs, Can anyone help how to draw it.

You want someone to teach you how to plot a parabola? (Hint: Exchange x and y. Hint2: Plot the two branches separately, so with two different colors.)

Hi Praveen,

I understand that you want to plot a parabola, you can use plot function to do that and here is a example to do that

x1 = -10:0.1:0;    % Define x-values for the first half
x2 = 0:0.1:10;     % Define x-values for the second half

% Calculate y-values for each half
y1 = x1.^2;        % First half of the parabola (positive y)
y2 = x2.^2;        % Second half of the parabola (positive y)

% Plot the first half in red
plot(x1, y1, 'r')
hold on

% Plot the second half in blue
plot(x2, y2, 'b')
hold off

xlabel('x')
ylabel('y')
title('Half Parabola with Two Colors')
legend('First Half (Blue)', 'Second Half (Red)')
grid on

Thank you Pratheek

wronfg this is not way to plot

Okay @Kaushal Soni, Can you show your correct way of plotting the 'backward bifurcation' branch?
