If you let `g`

be a tuple of expressions involving `t`

you can use the Python `*`

operator to use the tuple entries as your inputs `x`

, `y`

, and `z`

:

```
sage: g = (t, t^2, t^3)
sage: f = lambda x,y,z: (2*x, y+x+z, y*x)
sage: f(*g)
(2*t, t^3 + t^2 + t, t^3)
```

If you want to define both `g`

and `f`

as lambda functions you could do:

```
sage: g = lambda t: (t, t^2, t^3)
sage: f = lambda x,y,z: (2*x, y+x+z, y*x)
sage: f(*g(t))
(2*t, t^3 + t^2 + t, t^3)
```
