Why isn't the plot showing up? (new on programing)

x = linspace(-10,10,100);
y = @(x) (x.^2 + x.^2 + 3.*x)/(x.^2 + 4.*x + 5);
plot(x,y(x),'r','LineWidth',2)

Answer 1

x = linspace(-10,10,100);
y = @(x) (x.^2 + x.^2 + 3.*x)./(x.^2 + 4.*x + 5);  % element by elememnt division
plot(x,y(x),'r','LineWidth',2)
