syms x
f1(x) = x^2 - 4*x + 3;
f2(x) = x^3 - 4*x + 3;

then

fplot([f1 f2], [0 4])

or

fplot(f1, [0 4])
hold on
fplot(f2, [0 4])
hold off

[Federica Pucci]

if this function have the domain different, how do i?

for example:

f1(x,y) from x=0, x=1, y=0, y=1

f1(x,y) from x=1, x=2, y=0, y=1

i will summary this function and thier graohics.

fsurf(f1, [0 1 0 1])
hold on
fsurf(f1, [1 2 0 1])
hold off

Though in this particular case, that would be the same as

fsurf(f1, [0 2 0 1])
