Please don't do homework assignmets for students. It does not helpp them, only teaching them they can find the answer to their homework here, and we don't want that.

Hint -- use the plot() and legend() functions:

x = linspace(0, 6, 1000); % Define range for x as [0, 6] or whatever you want.
y = x .^ 2 + 4 * x − 6 % Your formula.
plot(
yDerivative = % Some other function of x.  I'm sure you know Calculus.
plot(   % Plot yDerivative vs. x.  Use a different color.
legend(
% Find slope at x=3:
yDerivative = % same function but use 3 instead of x
% Optional (unasked for) stuff to make the plot pretty;
title('y = x .^ 2 + 4 * x − 6 and its derivative', 'FontSize', 18);
xlabel('x', 'FontSize', 18);
ylabel('y', 'FontSize', 18);'
