Answer:
-1, 0, 2
Explanation:
we are given the piecewise function
and we are to find
. we need to find for each x-value, which interval/domain they lie in in terms of the piecewise function.
first,
is in the interval
because the
sign means -1 is a part of the interval (
meaning less than or equal to) , so
according to the function.
next,
is in the interval
, and so the corresponding value of
is
.
finally, we have
, which is in the interval
, and again, the
sign means 2 is a part of the interval. therefore,
.
