I get an error when I plot it

clc, clear

syms x;

f(x) = (x)
g(x) = (x).^2
h(x) = (x).^3
i(x) = (x).^4
j(x) = (x).^5
k(x) = diff(f(x))
l(x) = diff(g(x))
m(x) = diff(h(x))
n(x) = diff(i(x));
o(x) = diff(j(x));

figure(1)
subplot(2,6,1)
plot(f,[-2,2])
subplot(2,6,2)
plot(g(x),x)

I need help with subplotting all of this functions in an interval [-2,2]

figure(1)
subplot(2,6,1)
fplot(f,[-2,2])
subplot(2,6,2)
fplot(g(x),x)
