Why is my fplot not working?

My fplot is not working in my code. A few minutes ago, the code was plotting the graph just fine, but now it isn't. I can't figure out what is wrong. Matlab keeps saying that "Second argument must be a scalar or vector of unique symbolic variables."
%Symbolically find the roots of the following equation using 'solve'
syms x y(x)
y(x)=x^3+1
solve(x^3+1)
%Find what y equals when x=0
subs(y,x,0)
%Graph the equation on the interval [-10,10]
fplot(y,[-10,10],'b')

That’s the reason I always use figure to create a new one for each plot. Otherwise, MATLAB uses the existing axes.
