Answer 1

[Chad Greene]

If you mean y equals x cubed,

1. define an x array:

x = 1:100;

2. calculate y

y = x.^3;

3. plot

plot(x,y)

Answer 2

[James Tursa]

Do you mean y = x^3? If so, first pick a range for x, then calculate y, then plot it. E.g.,

x = 0:0.1:3; % From 0 to 3 in increments of 0.1
y = x.^3; % Element-wise power uses .^ 
plot(x,y)
