r is proportional to the square of b.
The rate of increasing or decreasing also we can say that the relationship between independent and dependent variables.
[tex]\rm r\ = b^{2} +1\\r\ \alpha\ b^{2}[/tex]
The constant can be eliminated because it does not affect the relationship

b is the independent varialble,
1 is constant
Here r is proportional to the square of b.
Thus, r is proportional to the square of b.
