Help with derivative problem

[solid tiger]

John is going to commit suicide. He goes on top of a building h meters tall. John's fall damage endurance level is 50. Let D(y) be the amount of fall damage caused with respect to the fall height y (in 1000 of meters) given by:
D(y) = 7y²+6y+37
What is the minimum value of h so that John will torn to pieces?

[nocturne seal]

I will summon the viata

@pale robin wahts the punishment for suicide questions?

[potent idol]

7y^2+6y+37=50?

so y=1 or y =-13

and y =1 means 1000 metres I think

y is in 1000 of metres

[solid tiger]

why set D(y)=50?

[potent idol]

because that's the most fall damage he can take?

[solid tiger]

it's not mine it's from my friend

[solid tiger]

ohhh

I get it

@potent idol thanks bro
