MATLAB: 2D contour plot

contour

I have two fucntions with identical independent variable x. I need to draw a 2D contour plot for that two fucntions. But my code is not runnig. Pl somebody help me.
syms x
y1=x^.3+x+1;
y2=4.*x.^2;
x=linspace(0,5,30)
[X]=meshgrid(x);
F1=y1(X);
F2=y2(X);
contourf(F1(X), F2(X))
This code is not runnig. I need to get a filled contour with F1 and F2.

Guessing about what you might maybe mean:
syms x
y1(x)=x^.3+x+1;
y2(x)=4.*x.^2;
x=linspace(0,5,30);
[X]=meshgrid(x);
F1=y1(X);
F2=y2(X);
subplot(1,2,1)
contourf(x, x, F1);
title('y1')
axis equal
subplot(1,2,2)
contourf(x, x, F2);
title('y2')
axis equal
