I never use ezplot() - I just specify the range and other options explicitly. You might try this:
x = linspace(-10, 10, 1000);
y = x .^ 2 + 6 * x + 55;
plot(x, y, 'b-', 'LineWidth', 3);
grid on;
title('y = x .^ 2 + 6 * x + 55', 'FontSize', 20);
xlabel('x', 'FontSize', 20);
ylabel('y', 'FontSize', 20);
ax = gca;
ax.XAxisLocation = 'origin'
ax.YAxisLocation = 'origin'
ylim([0, max(y)])
For additional customization options, see the attached demo.
