trying to lose all the text formatting noise, I get
f(x) = a x^r
satisfies f(2) = 1 and f(32) = 4
So divide the two given points, and you have
32^r/2^r = 4
16^r = 16^(1/2)
r = 1/2
f(x) = a x^r
satisfies f(2) = 1 and f(32) = 4
So divide the two given points, and you have
32^r/2^r = 4
16^r = 16^(1/2)
r = 1/2
