Show that f is continuous on (−[infinity], [infinity]).
f(x) =
1 − x2 if x ≤ 1
ln(x) if x > 1
On the interval (−[infinity], 1),
f is _____ a polynomial an exponential a root a logarithmic a rational function; therefore f is continuous on (−[infinity], 1).
On the interval (1, [infinity]),
If is _____ a polynomial an exponential a root a logarithmic a rational function; therefore f is continuous on (1, [infinity])
