1. y = k x^n maybe ?

if y = x^2 then n = 2

if y = x^3 then n = 3

3. y=k x^n (Directly proportional)

(i) y m^2 = x^2 (area of a square is x multiplied by x so “x^2”)
So “n” in that question would be “2”.

(ii) y cm^2 = x^3 (volume of a cube is x multiplied by x multiplied by x so “x^3”)
So “n” in that question would be “3”.

I tried to explain it more properly. :’)
