Hope it helps :) and let me know if you want me to elaborate.
The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³
<h3>Variation</h3>
x = k × w²
w = 4, x = 48
48 = k × 4²
48 = k × 16
48 = 16k
k = 48/16
k = 3
So,
x = k × w²
x = 3 × w²
x = 3w²
y = k/x³
x = 2, y = 14
14 = k / 2³
14 × 2³ = k
14 × 8 = k
112 = k
So,
y = k/x³
y = 112/x³
y = (1/112)x³
