How to Plot in specific interval

Hey! I cant figure out how to zoom a graph.

When I run my coding, the supposed interval from -5 to 5 is changed because of the bar graph. How do I change (or zoom) the graph so it only show the range from -5 to 5?

Thanks!

x = [-5:0.01:5];
y = x.^3 + 2.*x.^2 - x + 3;


dx = diff(x)
dy = diff(y)

slope = dy ./ dx

figure(1)
plot(x,y)

hold on
bar(slope)
