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
