To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67
10 total pieces of the pie
-5
-2
And only 3 remained so your answer would be
3/10
In order to determine which subset it belongs, we must rewrite

as



All these three numbers are irrational numbers, hence their product is also irrational
