. Find the derivative of 𝑦 = 𝑥^ 2 + 4*𝑥 − 6 at (3,5) and plot the function and derivative curves. Use the legend option for labelling the curve.

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);'
grid on
