which function represent the number of white tiles
looks like
total-red=white
total is normally x by x and red=x-2 by x-2
first one
test the given eqations
W(n)=4n+4
if n=which thing it is
first one has 8 tiles
W(1)=4(1)+4
W(1)=4+4
W(1)=8
corrrect
check top one
then the next one
the inputs are all natural numbers
last 2
check them
W(6)=4(6)+4
W(6)=24+4
W(6)=28
their thing is false
W(8)=4(8)+4
W(8)-32+4
W(8)=36
correct
ANSWERS
very top one
3rd from top (all natural numbers)
5th from top (continous fn)
last one
