Im trying to fill the area under a function but I dont know how to exactly do it, I want to plot the area between [-1, 1]
syms f(x)
f=1-x^4
f = 
t=0
t = 0
I=int(f)
I = 
Area=subs(I,1)-subs(I,-1)
Area = 
fplot(f,[-1,1])

x=-1:.001:1;
f=1-x.^4;
g=zeros(size(x));
plot(x,g,x,f);
x2 = [x, fliplr(x)];
inBetween = [g, fliplr(f)];
fill(x2, inBetween, 'g');
