Answer:
for X
Step-by-step explanation:
I dont really know sorry
(x/2)-16=f( x)
f( x)=2x+32
y=2x+32
inve.rse (switc.h x an.d y)
x=2y+32
subtr.act 32 on eac.h sid.e
x-32=2y
divid.e ea.ch s.ide b.y 2
(x-32)/2=(2y)/2
(x/2)-16=y
rev.ise y a.s f( x)
So.me wo.rd is sup.posedly ba.d an.d I do.n't kn.ow wha.t s.o I pu.t ra.ndom per.iods eve.rywhere.
If X and Y are two sets, then X × Y is the Cartesian product of X and Y, which is the set of all pairs (x, y) such that x ∈ X and y ∈ Y.
This means
A × A = {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3)}
