You need to use element-wise power - power, .^
epsilon = linspace(0,0.8,100);
sigma = 150*epsilon - 400*epsilon.^2 + 500*epsilon.^3;
figure;
plot (epsilon, sigma)
xlabel('Strain(ε)');
ylabel('Stress(σ)(kPa)');
title('Stress/Strain for Foam');
grid on;

Some homework assistance and solution:
x = linspace(0,0.8,1000);
y = 150*x - 400*x.^2 + 500*x.^3;
plot(x,y)

I believe that's solving the problem rather than assisting.
I suggest you edit your answer accordingly.
