Question
Show that the function is increasing and decreasing on the given open intervals. (Enter your answers as a comma-separated list if
necessary.)
y = x + 2; decreasing on (-*, 0); increasing on (0, ∞)
We have y'(x) =
x =
. Therefore, the critical numbers are
=
y'(x) 0 when x =
and y'(1) =
. Finally, since y'(-1) =
on (x, 0) and increasing on (0, ∞).
