13it has maxima at x=1
then when x>1
the function is decreasing
it will cut y-axis at y=1

1from -1 to 1 graph increases
from(-∞,1) graph decreases
from(1,∞)graph decreases
i will post graph quickly
62minima is 1/3
at x=-1
that you have not shown..
but still i will take this as a correct one :)
Congrats for your pink post ;)
