I wrote this code to plot a function
y=-1:0.05:15;
yprim= (0.75*y)-(0.05*y.^2)-((1.5*y.^3)/(1.25+y.^3));
plot(y,yprim)
hold on
grid on
xlabel('y');
ylabel('dy/dt');
title('plot of function(1) with b=0.05');
it keep giving me the wrong plot can i have some help

Well, what do you think is wrong? It pretty much is what you coded; now perhaps that isn't what you really intended but we can't tell that with nothing else to go on...

I'm guessing you meant
yprim= (0.75*y)-(0.05*y.^2)-((1.5*y.^3)./(1.25+y.^3));
Notice the ./ where you just had /
