slope = 
the slope is the value of f' (36)
f(x) = √x = 
f'(x) =
= 
f'(36) =
= 
Answer:
13 per minute
Step-by-step explanation:
so all those quadratics have their parent y = x², which has the graph of a "bowl".
and depending on the coefficient, the bowl is wider or not.
the larger the coefficient, the narrower the bowl, the smaller the coefficient, the wider the bowl.
well, 1/2 is smaller then 2, thus y = (1/2)x² is wider than y = 2x².
