making a non linear graf

hey I have no idea on how to make a graf of a diminishing value for an equation i made.

It's just to represent the degradation of a battery that has a loss of 2.3% per year like this:

100(1-0.023) I've tried the for funktion but Don't think i enter correct values

would appriciate the help

Do oyu have something to show? Can you attach the code? Picture

What is the equation? '100(1-0.023)' is just a constant value.

Hmm.. maby f(x)=n(1-×) P(×)=f(×)(1-×) and so on x has a known value now tho

Try this:

initialAmount = 100;
amountLeft = initialAmount;
maxNumberOfYears = 50;
for k = 2 : maxNumberOfYears
	amountLeft(k) = amountLeft(k - 1) * (1-0.023);
	fprintf('After %d years, the amount left = %.2f\n', amountLeft(k));
end
plot(amountLeft, 'b.-', 'LineWidth', 2, 'MarkerSize', 20);
grid on;
xlabel('Time (Beginning of Year)', 'FontSize', 20);
ylabel('Amount Left', 'FontSize', 20);
g = gcf;
g.WindowState = 'maximized';

Nice thanks! I really need to work on my loop functions.
