Differentiate the expression, then solve the inequality dy/dx > 0.
I tried, but the p in 8px makes it difficult to solve the inequality
It’s likely a discriminant situation.
We are solving for the range of values of p which makes y an increasing function.
Likely for all values of x.
So we put dy/dx > 0.
You will get discriminant < 0.
