I am trying to flip the last plot so it can fit into the other plots
f = @(x) x.^3;
g = @(x)x;
a = 0;
b =1;
fplot(f, [a, b]), hold on
fplot(g, [a, b], 'LineWidth',2)
xline(2)
ycoord = linspace(a, b, 20);
xcoord = [f(ycoord); g(ycoord)];
plot(xcoord, [ycoord;ycoord]), hold off
^^ this plot

Ran in:
f = @(x) x.^3;
ivf = @(y) y.^(1/3);
g = @(x)x;
ivg = @(y) y;
a = 0;
b =1;
fplot(f, [a, b]), hold on
fplot(g, [a, b], 'LineWidth',2)
xline(2)
ycoord = linspace(a, b, 20);
xcoord = [ivf(ycoord); ivg(ycoord)];
plot(xcoord, [ycoord;ycoord]), hold off
