29: D( f ) = (−∞,0) ∪ (0,∞);
f is continuous
there.
y-intercept: f (0) not possible;
x-intercepts: f = 0 gives x equal to minus
third root of 4.
f is not symmetric since f (−x) is not equal to
f (x) nor to -f (x) (try e.g.
x = 1).
Limits at endpoints:

Interpretation as asymptotes:
No horizontal asymptote at
−∞, but a chance for oblique.

Asymptote y = x there.
Vertical asymptote at x = 0.
No horizontal asymptote at ∞, but a chance for oblique.

Asymptote y = x there.
Now determine monotonicity using f ′.
