y = 9
Step-by-step explanation:
Given y is directly proportional to (x - 1)² then the equation relating them is
y = k(x - 1)² ← k is the constant of proportionality
To find k use the condition x = 5 when y = 4
k = = = = , thus
y = (x - 1)² ← equation of proportion
When x = 7, then
y = × 6² = × 36 = 9
