Answer :
we only know the value of f(5)
therefore we need to figure out what we would put in for x in f(1/3 x) to get 5
set
1/3 x=5x=15
now if x= 15 then f(1/3 x)
= f(1/3×15)
= f(5)=8
and so
1/4×8−2=2−1=1
therefore the "corresponding point" is (15,1)
now if x= 15 then f(1/3 x)
= f(1/3×15)
= f(5)=8
and so
1/4×8−2=2−1=1
therefore the "corresponding point" is (15,1)
