I am trying to plot the following function in Matlab. y=x^3+2x^2-6x with x having bounds of 0 to 30 (0:30)
I am using the following code and below is the error message I am receiving x=0:30; >> plot(x,'x.^3+2x.^2-6x'),grid Error using plot Error in color/linetype argument
If someone could please help me to fix this error and/or see the error in my function I would appreciate it.

x=0:30;
plot(x,x.^3+2*x.^2-6*x)
grid
xlabel('x')
ylabel('y')
title('y=x.^3+2*x.^2-6*x')
